anybody running j-stocks on the street?

[JRKOUPE]

bilsteins (billies might be the gayest term I have ever read) do not perform well with stiff springs, and J-Stocks are fucking crazy. You will need to get a revalved shock to work correctly with J-Stocks. I have GC 475/650 springs, and I was having under-damping problems in turn 10 at Putnam a few weekends ago on OTS Bilsteins.
Sending them off to Bilstein in a week or so.

try to get over it......they have been called that for years...

Based on your response, I think I will try IE3s with bilsteins and shortened/stiffer bump stops as that seems to be the problem creating the harsh feeling of the bilsteins.

cool, thanks

Did someone try shortened/stiffer bump stops, or is this your own idea? I agree that the front end will bottom out on the bumpstops with IE3s, but I didn't know you could change the bump stop to fix it. How do you do this?

I have Bilstein sports and H&R Race springs. On moderate bumps, it's fine. On big bumps "Wham!" It seems like the dashboard is going to fall off and the struts are going to punch through the towers when the front tires hit a big bump. The front shocks must be bottoming out. BTW, I'm driving on Detroit's frost heaved highways every day in my 325IS.

I run on GC stops.....harder /shorter...12 bucks each....I sound like a recording. Ya know the billies may also be problematic w/ shorter hi rate springs!

Yea, but the front Bilstein bumpers are inside of the strut. They are at the bottom instead of at the top. Bilstein struts are inverted so the oil filled portion is at the top, mounted to the shock tower while the shock rod is at the bottom, inside the strut housing. You would have to disassemble the Bilstein shock somewhat to get to the bumper. The GC bumpers would probably not fit inside of there. That's why I wanted to know if Bryson has an idea about how to change the Bilstein bumpers, and if this really solves the problem.

Bryson stated that he lives very close to the bilstein factory. Im sure that while he is having them revalved that they will replace the bump stops. I actually didnt know they were in the strut, now my question is answered.

[Bryson]

rumor has it that bilstein does indeed have a shorter and stiffer bump stop that they will install for you while revalving your shocks if requested. If I don't go this route, I will probably buy some thick rubber ~1.5" and cut it to the appropriate size and install in the front shocks, doing the same with the rear, though the rear is a bit easier
