Im getting some squeeks from my rear suspension...should i go with some polyurothane bushings, or is it from something else? Also, how bad does the bottom out if i go with eibach springs (estimated at 1.5-2 inches lower)? One more...Who makes the best SFC's? SLP?

 

I have all BMR stuff. As for best, I would probably say Kenny Brown Double Diaminds (DD's). But those get in the way of after market exhaust and torque arms. I would get BMR's boxed design. That's what I have and the car is super rigid. As for the bushings, if you don't put grease on poly, it will squeak. The poly will be much stiffer than stock and make everything a little tighter. Depending on the component, it can induce a little road noise.

 

SFC's? I love my KBDD's.

if you go with poly you'll probably have more squeeks. Just check the torque specs on everything in the rear to start with, and clean up then greese any poly you already have in there.
