I have a 94 z28 with 315's in the rear and 275 in front. A problem I had with passenger rear tire is that it was getting chewed up from the axle torque . Bought new tires and put in adjust. lower control arms and adjust. panhard bar as well as Eibach drag launch springs to make sure i don't have the same issue again. Now with the eibachs the wheel well gapis pretty bad. Iknow they werent supposed to lower it, just didnt think it would raise the car that high.I've had recommendations to cut down a section of the coils to help. Can that work? Anybody ever used eibach drag launch springs before? I just want to know if after some miles they level out slightly. Thanks.

 

Did the springs come with air bags? If they did, just inflate the one on the right side, and the car won't ride as high.

 

I have drag launch springs and they do raise the car bit and most likely won't settle down, I cut a coil or so off of mine.

 

If it is chewing up the tire you might try a different style anti roll bar, my car will almost pull a rear tire when I corner hard =)
