87C4 coupe---I have had the car for about 8 mo. now. Walking up to the rear of the car in the parking lot i noticed that it wasn't sitting right. The left rear is sitting lower then the right (about 2 inches higher on the right side (FENDER WELL TO TIRE). The front seems to be equal on both sides. At home the car is never parked on a level surface so i never noticed it before. No noises when i hit bumps. What should i start looking for ???

hey, got that FSM yet?
shocks cause it, I have heard. when I removed my old Bilsteins, rr set up about 1" higher than before. I thought shocks were bottomed out, but got them loose at btm and they had plenty of travel.

Spin the rear spring around 180 degrees. This will tell you if you have a worn spring. Maybe the driver was 350 lbs. 25 years of fat will make a spring uneven.

There was somebody that used duct tape to fix the problem.
The guy with the duct-tape wallet maybe?
Knowing this was an issue and having had the experience first hand, I was proactive this time...
I took my nice new hard spring and plasti-dipped it and coated the entire composite surface with the rubber coating. This protects it from any degreasers that I might use to clean the underside. Since so many automotive cleaners are caustic or acidic, the rubber coating prevents contact with the composite. So far there have been no issues. All it takes is one splash of certain common chemicals on the spring and it WILL crack...

I can believe it. Most plastics will crack from acetic acid, common vinegar, also from many common household cleaners. Refrigerator liners in the test lab would crack like a pistol. Generally, it was small stress cracks, like the lines in one's brow.
