It works, it works well. That is all.

Seriously though. The BC BR’s, as we all know, is one of the most affordable CO’s for the V36. When BC first got these out, they had issues with the top mounts that caused rattling and other things. By the time I got my set, these issues have already been addressed.

Needless to say, I never had any problems with the BC’s. They’ve been quiet, reliable and offered the performance I expected from it.

My set had 12k/(extended)8k springs, which works rather well especially on track, however for daily it can get quite taxing -- especially in Houston moon-crater roads. After all this time I finally bit the bullet and swapped those springs with Swift’s at 10k/6k (more on that in a later post) -- i am getting old and would like a more comfortable ride. BC allows customization of spring rates as well as length. On a new order, they'll match the dampers to those rates. For spring swaps, if you're within 2-3k of the original damper valving, you're good to go. Otherwise, they recommend re-valving the dampers to match.

I never had the dampers dyno-tested, but they work fairly well for both these spring rates IMHO, and each damper does get tested at BC’s facility (if you pull up the sleeves, there’s a sticker with the results right on the housing itself.) At full-stiff, they ride like on rails and really is suited for smooth roads, otherwise it’s bumps galore. At full-soft, it’s as soft as you’ll ever want to the point of being slightly bouncy. Chances are you’ll never have it both ways, but it’s good to have the adjustability. 2 clicks at a time offer noticeable changes in dampening, which IMHO makes it realistically a 15-way adjustable set-up. Then again, my butt dyno is not that well calibrated.

I typically have it at 1/3 towards the soft side to allow for some suspension movement, even on the track (which isn’t entirely smooth either.)

Another advantage of the BC’s, especially for the price, is that height and preload adjustments are independent of each other. You can go as high or low as the set-up can provide and still be able to dial-in preload all around. This is not only useful for daily driving, but also to tweak corner weighting and performance.

Customer service is also quite excellent. They’re always within reach either by phone or e-mail. E-mails are always answered within 24 hours, usually much sooner. I experienced this pre-sales, post-install and just recently again in the process of swapping the BC springs with Swifts.

Overall, I’m quite happy with the BC Racing Br-Type coils for our G’s. Some people may swear by 2-3x more expensive set-ups, and I’m sure those are great set-ups as well, but for my budget and type of use, these have proved to be a good buy. The quality is also certainly not 2-3x lesser.

p.s. Some of you may note I recently posted about front-end suspension noise, I do not believe it to be related to these coilovers as the noise started exactly right after I swapped the springs, which could mean I didn’t put things back together properly, twisted some bushing or something else is amiss (for sure, apparently, my endlinks need replacement, and it sounds like my leaking steering rack and/or control arm is also acting up.)

 

Good review!

 

Thx for the info.. iam ineed of some help I got a 07x with tein stech on an the ride is **** so it's either coilovers or new shocks

help needed

 

Thanks.

p.s. I figured out what the newly developed squeak is. Hopefully this will help anyone else who may encounter it after upgrading to the Swifts.

Can you describe what the ride is like? Bouncy? Bumpy? Lack of control?

 

Are you on the extreme drop version or the standard version? I am looking at

getting either stance gr or the bc br extreme drop and I was wondering what spring

rates would be best. It will be mostly daily driven on sub par roads and taken to the

dragstrip occasionally .

 

I think it's just the regular version, not entirely sure.

If you plan on slamming the car to the ground, you need to get stiffer spring rates.

And update, looks like i spoke to soon on the review. Just 3k miles after putting the Swift upgrade springs on (lower rates) my front and rear passenger side dampers are goners --- both are squeaking and the rears take forever to rebound (compare to the driver side anyway.)

The squeak started right after the upgrade, and i though i fixed it after greasing certain points. It came back after a few rainy days. My initial thought was the grease wore off, but the squeak got progressively worse on the passenger side.

Took everything off this past weekend to diagnose.

Until i can fix it, i put on a new set of GR-2's and Swift Mach lowering springs.

 

Wow that is good. How much did you drop your car on these?

 

Not a lot, the car sat at roughly 26.5 - 26.75 around.

Considering the roads i go through (including washboard-type ones -- on the freeway!) and track duty earlier on in its life, i guess 43k isn't too bad.
