M2 Competition: BC BR Racing Coilover Review & Installation

Back in early August, I made the decision to purchase a set of BC BR Racing Coilovers with the Swift Spring Upgrade (12k Front/16k Rear). About a month and a half later, they finally arrived! (Thank you Original for being my preferred dealer!)

Why: For any "regular" coilover (adjustable height with dampening), I believe BC BR's are the best bang-for-the-buck considering it comes with camber plates, ability to custom-build your set, and dampening. After having owning/daily-driving sets of KW V1 mated to Ground Control camber plates, AirLift 3P, and H&R Super Sports - I've realized that for a majority of the time if you just need the basics BC's will do everything you need to do well. KW's are great, but do not allow for full adjustability (or perhaps not enough for me), plus I did not want to have to go out of my way to purchase camber plates. Furthermore, I daily-drive my M2C and occasionally track it so I needed something that can be efficient.

First Impressions: Again, to preface I have owned KW and AirLift and have also been fortunate enough to install Ohlins and Bilstein on other friends cars. At first glance, they are well made but not to the standard of KW. I'd say it is an ~8.5/10 for build quality, it is good but not great. Some small plastic bits and what not but overall good.

Installation: Honestly, it took me a cumulative of 5.5 hours by myself. I'd say this is a 6/10 difficulty installing. Some things to note that I found useful to pass on, the rear section of the exhaust is recommended to be removed if you would like to use an impact on the rear spring perch arm bolt (although you can get away with it by using a really long extension or just using some sort of wrench to remove it). Also, you don't need to fully remove the aluminum brace either - simply take off the side bolts and loosen the two bolts by the windshield.

P.S. - For ideal height, on these BC's, drop the front 2" from the preset and the rear fully max out the height adjuster AND the shock, that should roughly put you at a good starting point before having to readjust the coils when they settle.

Review: For the money, not a bad choice for coilovers. If you go with a 10k/12k spring rate like how they normally stock their BR coils with, it’ll feel about the same as stock. I did 12k/16k Swift springs - it feels just marginally stiffer than stock (~10% stiffer than OEM). I’d take this any day over KW’s if you consider what you receive vs what you pay. However, KW Clubsports take the win if you consider the best-of-the-best. But that’s a different topic. For anyone looking for street/occasional track use, I’d buy these… That being said, the quality is good but not top-notch. So if you have a deep pocket, look elsewhere if you have those means available. As far as lowering ability goes, maxxing out the rear springs will tuck tread, but not tuck tire. As for the fronts, there is plenty of adjustment. Consider this an initial impressions after installing. I’ll report back and update this thread when everything is settled and dialed-in.

Out of the box, this is what you should expect (I will upload higher-quality pictures tomorrow when lighting is more appropriate). I will post a basic guide and any references that others may find useful if they choose to install on their own.
