I am looking to do some coilovers in the spring. I have been looking at both the BC Racing coilovers with a Swift spring upgrade or a set of Bilstein PSS10s. Does anyone have specific experience with both to let me know which is a better choice? Bilsteins are a bit more money, however are a lot easier to install/adjust as the adjusters are bottom mounted in the rear. BC is cheaper, but cutting a hole and routing the adjuster extenders may be a hassle. Anyone have driving impressions of the two? Long term reliability?

 

I've been reading up on the same 2 coilover systems for my R53 as well but I keep going back to considering the KW V1's.

Looking forward to the responses.

 

Have a talk with Colin at greeneperformance.com.

 

I was almost betting on this comment. What benefit do the Greenes coilovers have. I know it is different valving, but they also cost several hundred bucks more.

 

"Give Collin a call."

I too wonder what help that reply gives. It is like I desperately need some fund and someone said "give Wells Fargo a call".

No disrespect for Greenes Racing. It is just a useless comment from the poster when I suspect the firm makes more money selling BC Racing over the counterpart.

 

No one has experience with both?? Just trying to make an educated decision. Also if anyone knows what makes Greene Coilivers better let me know. It looks like they are about $600 more than BC if you factor in the camber plates.

 

I've got a set of PSS10's with Swift 330# springs front and rear. The upgrade from Konis is amazing, I picked up 1.5 sec on the first AX that I ran with them, set at 5 on a scale of 10. At the moment, Tigger sits just a tad too low and my tires are rubbing the edge of the inner fenderwell away. That's all setup and irrelevant to your question. Depending on how you set up your ride height, you should plan on getting a set of lower rear control arms. Without the lower arms, I've got -2.5* camber at the rear, where -1.5 is optimum. I really like the PSS10s, though for a DD, the 330# springs are a bit tight for most people. I had the Koni Sports front and rear, and didn't like that I had to drop the rear shocks to adjust them, with the PSS10s, I can do it just by reaching under the car (granted I have to lie on the ground), which makes adjustments between runs easy-peasy.
I do have the Bilstein progressive springs in case you're interested. Never been used.
