the only rear coilover kit you should be thinking about is from maximum motorsports. i hade their full coilover kit front and rear with bilstein shocks and the ride was great with zero noise. i also had no problems with rubbing on the frame or tires and this was with 18x11" wheels and a 315 tire. your
lower control arms will still be used however you just wont have the spring setting on it. how do you drive your car? if you drive it hard in corners or something along those lines one thing i will recommend is that you do both the front and rear at the same time. with coilovers simply in the rear, or the front could make your handling somewhat unstable in a tight situation. this is coming straight from the MM website and they know a thing or two.
