The BC Racing BR series coilovers by JM Auto Racing are the perfect choice for street driving with a dash of weekend warrior track action with your car. These coilovers feature easily accessible adjustment knobs for dampening and separately adjustable ride height settings. The BR series makes adjusting and maintaining your performance coilover system easier than ever. Ride height is independently user adjustable so you can dial in the exact look to reflect your driving style and performance needs. BC's patented concave lower locking ring keeps all adjustments locked in and ready for precise predicable performance in any scenario. BR series coilovers are a strong, complete and attractive coilover system at a great price.

BR Series Coilover Features:

  • 53mm Dampers (Larger than the Competition)
  • Fixed cup/locking collar design
  • Mono-tube shock design
  • Full height adjustability through the shock body (not spring)
  • 30 levels of damping adjustment (compression/rebound)
  • Custom spring rates available as well as a SWIFT spring upgrade (upon request).
  • 1 year warranty against manufacturer defect
  • Completely rebuildable and individual parts are available separately for purchase.
  • Full set included - 4 coilovers

 

 

The BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity.

 

As the damper unit opearates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.

 

BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their BR range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.

 

 

 

 


 Corner weight adjustment:

The lower spring platform of the BC Racing coilovers are adjustable. This allows the car to be set up for corner weighting to achieve perfect balance and ensures that maximum tyre efficiency is achieved.

The car needs to be placing equal weight on each tyre on an axle so both front tyres need to be taking equal loading as do both rears. This makes sure that both tyres are doing their equal share of work when cornering which increases overall grip, maximises corner speed and reduces lap times.

Optional assister springs can be purchased to allow wheel droop to be dialled into the unit to suit specific needs.

 


Ride height adjustment

Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment from near standard ride height to so low it wouldn’t be drivable on the road.

Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run.

 

 


Damping adjustment:

BR coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.

By tweaking front and rear damping you can adjust the way the car handles. Increasing damping force on the rear relative to the front, for example, will start moving the vehicle into a more oversteer orientated stance.

If you want to go drag racing in a rear wheel drive car then you want the back of the car to squat off the line to maximise weight transfer to the rear and therefore onto the rear tyres. This maximises traction and helps prevent wheel spin. To achieve this you would soften the rear dampers to allow faster compression. If you had the rear dampers set to hard, as you might run the car on a race track, then the car would be less inclined to squat so traction would be reduced.

Conversely, if you want to go drifting and are finding it hard to break traction and are having problems with understeer then making the rear dampers harder will help reduce traction whilst making the front dampers softer will give greater front traction. This will make the rear of the car looser whilst minimising understeer thus altering the vehicles handling characteristics more towards drift than drag, road or track.

 


Pillowball (rose joint) upper mount:

Many of the BC Racing BR coilovers come with pillowball upper mounts. The mount itself is made from aluminium alloy, anodised and then bead blasted to give a high quality, durable finish.

The pillowballs themselves are of Japanese manufacture and their solid nature eliminates any flex or play associated with the standard rubber mounts so improving response and handling.

 

 

 


Camber adjustment:

If its possible to include camber adjustment on your vehicle then the BC Racing coilovers automatically include camber adjustable aluminium pillowball top mounts. These feature the same high quality Japanese manufactured pillowball but give the added benefit of an adjustable top mount that allows camber to be set to suit your needs be it road, track or drift.

 


 Corrosion protection:

The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminium components (top mounts, locking collars etc) are anodised and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard.

 


High quality coil springs:

BC Racing coilovers only use the highest quality steel for their spring manufacturer. They are produced from SAE9254 high strength durable cold wound steel.

The springs are compression tested through over 500,000 cycles with less that 5% deformation.

 

 

 

 


 Patented concave lower locking collar:

Coilovers use a locking collar to prevent the bottom mount becoming loose. If the bottom mount becomes loose then the damper body can work its way down into the bottom mount so reducing ride height on that one corner which can lead to dangerous handling characteristics. This is a very common problem for coilovers in general. BC Racing utilise an innovative and patented designed lower locking collar with a bevelled edge that seats into a corresponding bevel in the coilover bottom mount. This vastly increases the surface area that the locking collar works on and so prevents the common and dangerous problem of the locking collars working loose.

 


 High quality oil:

BC Racing dampers use a sophisticated shim stack design and high quality oil to consistently control the compression and rebound speed of the damper rod even under the most extreme conditions.

As the vehicles travels over rough ground the compression and rebound motion of the damper rod heats the oil. Poor quality dampers use cheap oil whose characteristics alter with varying temperatures. Its vital that high quality oil is used that can maintain consistent viscosity under a wide temperature operating range. Once the oil start to degrade, its properties change leading to damping changes leading to changes in the vehicles handling characteristics.

BC Racing ensures that only high quality oil is used so that damping rates are maintained not only for the moment in hand (i.e. whilst out for a back road blast on or track) but that long term longevity is maximised with oil that doesn't degrade quickly over time thus extending the dampers operating life significantly.

 


 Nitrogen pressurised dampers:

When you work a damper hard on track or on high speed bumpy roads you can cause the oil to aerate and cavitation can occour. This causes foaming which effectively reduces the oils viscosity and so reduces the units damping effect. High quality oil goes a long way to help reduce this problem but BC Racing go one step further and pressurise the dampers with nitrogen. The nitrogen exerts a pressure on a floating piston which in turn exerts a permanent pressure on the oil dramatically reducing aeration and so improving the consistency and quality of the damping. The pressurised nitrogen also adds an additional element of effective spring rate to the damper unit.

 


 Bearing mounted upper spring platform:

Because the spring twists as it compresses it is very important to minimise stiction between the spring and its seats. If this tension is not relieved then spring binding can occur leading to the spring rate effectively altering slightly as the spring compresses and extends. The tension generated can lead to rapid deterioration of the spring pearches and in extreme cases can cause the spring platform and locking collars to loosen. This can lead to the platform and locking collars "walking" down the damper resulting in un even ride height and danger of the spring dislocating under full damper extension.

The friction between spring and seats also has an effect on steering effort as the springs are physically turned with the wheels. This introduces additional unnecessary friction into the steering system which has a knock on detrimental effect on the vehicles handling characteristics.

The bearing mounted upper spring platform is one of BC Racings innovative designs. By vastly reducing stiction between the spring and its seats the BC Racing units avoid the above problems thus improving the efficiency of the steering system and allowing the spring and damper to work as designed.

 


 Optional upgrades:

 Damper adjusting extenders - to save you the time and trouble of removing the parcel shelf each time you want to adjust the damping on your BC Racing coilovers we can offer pairs of adjuster extenders. These attach to the adjuster knob on the top of the coilover and are available in three lengths, 110mm, 200mm and 250mm. They attach in seconds with a simple grub screw design.

Assister spring perch - you might prefer to run some droop with your coilovers or maybe you want to alter the ride by adding an additional smaller assister spring. The spring perch and assister springs allows you to do this. The springs are available in a wide range of spring rates.

Pillowball top mount - some applications come with hardened rubber top mounts as standard to ensure the highest quality ride and keep costs as reasonable as possible for road use but we often offer a pillowball upgrade for these vehicles should you want to remove this flex and make the car a little more hardcore. Upgrading to pillowball eliminates the flex inherent in even the hardened rubber used by BR Racing so improving the handling for those looking for the ultimate.

 


Warranty:

BC Racing has the best warranty in the industry. Your purchase is completely protected from any defects including blown shocks within the first year. If something should happen after that, we stock all replacement parts at incredibly low prices (Cheaper than rebuilding), that will be available to you in a few days rather than weeks.Our goal is to get your car up and running as quickly as possible.

Great and Easy to Use!
Size: 11S
Background: I have a shedding dog, so I bought this in hopes that by running it every-day, it would pick up on some of the dog hair on the floor. What I like: -VERY easy to use. -easy to follow instructions -has a sticker on the bottom so if it ever stops and beeps, you can flip it over and it says exactly what the beeps mean (one beep means one thing, two beeps means another--which is SUPER helpful!). -color on top clearly shows what mode it is in (blue-ready to go, orange-needs to charge, red-problem to fix-such as emptying the tray). -very quiet. I can work on stuff with it in the room and it does not bother me at all (my dog also does not mind it). -works great on white carpet and easily transitions from my living room to dining room (which has a slight bump). -when its low on battery, it does not die where it is at, it just turns off the vacuum then finds the home doc and charges itself. -just works really well. I run it everyday and I am impressed by how much stuff it gets (especially when it goes under things such as the couch). -if it gets caught on a cord, it usually takes 5-10 seconds but then it stops the suctioning and moves away (releasing the cord or other item). However if you have a small cord you should put it up (and you should regardless, I just noticed it doing this a few times and thought it was neat, but I do try to pick up all cords). What could be improved: -nothing really in particular to this. -It does not work well on anything black, but this is true for all robot vacuums. It sometimes gets stuck when it goes on the black carpet we have with the black chairs (I suspect because it can not detect them), but this has not happened often. My dog has a black mat for her food and water and it always bumps into it and spills the water, but again, this would occur with any robot vacuum. -Also, make sure the doc is against a wall because otherwise it will move and never charge (self explanatory, but I did not do the first time and it kept trying to doc and was just pushing the doc around the floor). -Finally, you do have to dump out the vacuum particles almost every time you run it (if you do a full circle/battery cycle). It is really easy to dump and beeps when it needs to be emptied. Again, nothing really negative, just something to note. Overall, I really like this! It does a nice job cleaning up the dog hair and other things that get on my floor and saves me a lot of time not vacuuming daily. If you have a dog, I would watch them with this first before you use it. My dog was initially scared of it but sniffed it's "butt" and now they are cool and she does not mind it at all. Pleased with this product and would recommend! :) **UPDATE** On another note, Eufy has amazing customer service! I received an email from them addressing each of my "what could be improved" components with more information on the product. Very impressed.

ROB is amazing.
Size: E25 Black
I have to first explain that I have named my E25, his name is now ROB and will be referred to as ROB going forward. ROB has been an amazing addition to our family and yes I said Family. ROB was easy to set up, all instructions were clear and easy to follow. The first day, I followed ROB everywhere afraid he would get stuck on a rug, or would have difficulty making it over the transitions of our flooring. But ROB had no problems what so ever. And honestly, I found myself amazed at the quality and endurance of ROB. He was jumping over transitions, flipping from mop to vacuum at the proper times and would suck up a dog hair bunny from 3 feet away! As a home with 2 big dogs (over 100 pounds each) that looses enough fur to make a new sweater everyday, ROB has done an amazing job! It’s been a week with ROB and I have found that he takes no prisoners, there was an area that I didn’t want him going into because I had boxes laid out, I was lazy and just made a make shift barrier so he wouldn’t proceed through the area, but ROB was persistent and was able to move the barrier so he could do his job. So, if you want a robot that will jump a shoe wall, ROB is your man! ROB navigates around a dog toys, around dog bowls, and can even get rid of the doggy dribbles when they drink. I have ROB set up to vacuum during the day and at night, he vacuums and mops. My 2 dog sons and my family are all happy with ROB as he is quiet and doesn’t scare them. Most days they just watch ROB do his magic on our floors. ROB also cleans himself, he will run home to clean his butt after mopping and will empty his own debris from his vacuuming. I really don’t know how I survived without ROB this long!! I waited 6 months before I finally purchased ROB after seeing his brother BOB in action at my Cousins house. So don’t be like me and wait, just make the purchase. You won’t regret it.

Probably the best robot vacuum mop you can buy in this price range
Size: E25 Black
Its pretty solid device. Honestly its so smart that it vaccumed and mopped my bathroom and ofcourse the wet hair stuck on the wet floor wasnt vacuumed the first pass but it then waited for the second pass to pick it up when it was dry. Made my entire house look so clean its actually amazing. It actually mops and get all the corners with dust. One thing thouhh is the side brushes tend to get tangled with hair and thread but uts very snap on snap off brushes so removing the stuck hair is super easy and only sometimes happens. The suction is amazing too its very strong. It moos the floor with clean water with solution so its actually cleaning well. Overall 10/10

The best vacuum cleaner ever!!
Size: E25 Black, Size: E25 Black
⭐⭐⭐⭐⭐ I honestly couldn’t be happier with the Eufy E25. I actually own two of them, and they’ve completely changed my daily routine. After spending a lot of money trying different brands, I finally found one that truly delivers everything I need in a vacuum. The suction power is impressive, it handles pet hair and debris effortlessly, and the mopping feature actually works (not just a light wipe like others I’ve tried). The self-emptying and self-cleaning system is a game changer—it saves so much time and maintenance. Navigation is smart and reliable, and it rarely gets stuck. It covers my floors efficiently and leaves everything noticeably cleaner. I also love how low-maintenance it is overall. If you’re tired of wasting money on vacuums that don’t live up to expectations, this is absolutely worth it. For me, it has truly been life-changing.

Updated 1/28/2020 update 1/17/2020 It's been everything it was advertised to be and more. (Not)
Size: 11S
I called Amazon again today. Explained the situation and that no one from Amazon or Eufy had returned my calls as they promised. Also after replacing the battery at my own expense it ran 90 minutes again but got stuck everywhere, made this weird ratcheting type noise every time it changed surfaces and finally today just beeped at me twice and died. Supposedly that indicates a seized brush but they all spin freely. This time I just flat out asked them to look at my Amazon account and replace it, as I'm a very good customer. New one will be here tomorrow. I'll do a separate review on that one as it took me forever to find this one again. I'll also let you know if it's a refurbished unit or not. Well wouldn't you know it. I leave a nice review and a few days later, Murphy's law rears it's ugly head. Device is 3 months old a couple weeks out of the exchange warranty and the battery is shot. Runs 5 or 10 minutes on a full charge. Called Amazon to see if since I am a really long standing customer if they'd help me out. Nope but we'll call Eufy support on your behalf and they will call you. We will also call you to follow up. I've been a customer service manager a lot of years and this is where employees can kill you. This Amazon person made me multiple promises. It's been a week no call from Eufy, no call from Amazon. You just turned 4 stars into 1 and if this is all the longer the batter lasts don't bother because the replacements are $25 to $30 bucks depending on the brand. I'm not spending a hundred bucks a year on batteries and this thing should be under warranty. After 3 days I ordered a new battery and Rosie is running again but I'm no longer pleased and the next time I'll buy another brand. If if this battery doesn't last the whole thing goes in the trash and I buy something else. I run this every day maybe the batteries won't take that I don't know. But if you're going to run it every day buy something else. This didn't last long enough at all. I wanted to wait a while to be sure I had a good sampling and could post a fair and useful review. It's been 90 days now. We have two large (bigger than standard) labradoodle puppies. 85 and 50 pounds and they're 1st generation so they shed a lot. They also, being puppies, have tore the yard up so it is basically a mud pit and they wrestle, run, and fight constantly. They put a lot of dirt and hair on the floors and in the air. We run "Rosie" every day. Yes my wife named it. It does an amazing job on our hardwood floors and throw rugs. It gets all the hair and an incredible amount of dust and dirt. What I mean by that is we can run our Dyson or the Shark Pet vacuum and then run Rosie and the chamber will be full of dust and dirt when she's done. It's almost disconcerting to know our very expensive upright vacuums leave so much behind. It also has the unadvertised ability to buff our hardwood floors. They shine when she's done and the beater brush is showing no signs of damaging the finish on our floors. I would disagree with some of the reviews and even the manufacturers assertion that it doesn't work well on dark floors. Our hardwood floors are a dark reddish brown. The device works great on them and as I said when it's finished they shine. We have agreed we will never be without one and love this device. It does everything it has been advertised to do and more. Also it is set to automatic power and runs longer than the advertised time on a full charge. We get about 2 hours and 15 minutes. We've put down an additional 6 throw rugs for the rainy snow season in the path where the dogs run when they come in and the time has dropped to around 90 to 100 minutes. Still long enough to cover everything well and more than once. It does keep going until it needs a charge it doesn't just run and go back to the dock. I've noticed in the open areas like our living room it might hit that 2 or even 3 times. The floors are like glass after that. Now for the negatives, and these are not deal breakers I'm just being fair. The dirt and dust I referred to is new to us. we recently moved from Illinois to Ohio. In Illinois the dirt is black. Here it is red or a very light brown. The vacuum gets externally dirty. It gets covered with dust/dirt and does not look good. The device is black and the dust is light colored and is readily apparent. I don't want to put it away all the time or for company so thats a problem for me and more cleaning which is not advertised so I'm mentioning it. Secondly it needs to be emptied every use or every other use. They are all like that except some of the super expensive robot vacuums so I wouldn't mention it except for my third negative. It is hard to clean from a mess standpoint. Not so much with the pet hair but with the dust. When you dump it the dust goes everywhere. Unless you have an empty trash can so you can get it way down inside when you're done the garbage can lid and sometimes the floor around the garbage can is clearly dusty from emptying the vacuum. The filters need to be removed at least every other running and they are also a big dusty mess. I also don't believe they will last as long as advertised. I have an air compressor in the garage and a hand held electric air compressor and use those to clean the filter. The foam piece I rinse in the sink. I don't think that someone without access to those tools is going to get the life out of the filters thats advertised. The device comes with a set of replacement filters and the rotating brushes. Not the beater bush though. Our unit is 3 months old. I had to replace the filters at about 40 days and tried to make them last a little longer this time but it hasn't worked out. The outside of the device is filthy. I believe this is due to the filters. The brushes have lasted longer than the suggested replacement time. They are 90 days old and still look like new. Last and has been a rare negative. The device will get stuck under things. Once I learned what the obstacles were in our home it was easy to fix. Some areas I blocked with rolled up moving blankets. I pull the chairs out from under the kitchen table to allow room for it to maneuver. If I don't it gets under there and spends way too much time cleaning and trying to get out. I'd rather it spend less time under there so it can do the whole cleaning area and have power left to do it again. I had the problem spots corrected and figured out within the first 30 days. I've read some units have a tape or something the vacuum will sense and avoid. I wish this unit had that but then again at this price point that is probably an unfair expectation. So those are the pro's and con's we've encountered. The con's are all minor irritants and not a reason not to buy the device as all of these devices are prone to these issues except one or two of the very very expensive units. To repeat what I said earlier this device has worked out so well we have decided that we will never be without one and that when the time comes to replace her we will not feel bad about spending the money for a high dollar unit as it is worth it. Time is worth more to us than money and this thing saves us a great deal of time. It does great job, has done no damage to anything, and if it weren't for the clean up issues would be a five star review. I hope this helps someone make an informed decision and I hope you buy one. It's an amazing little machine, stands up to all the reviews, and truly is the best bang for your buck in robot vacuums.
