Bought car used and it rubs on the right while going over RR tracks and bumps. Although everything looks good the car sits 1/2 inch lower right rear and 1/4 inch low right front. Further inspection reveals new parts right rear and paint. It was in an accident. Who ever fixed it did not do it right. I am wondering if I should replace rear springs and shocks and see what happens-not cheap about $900. Should I get aftermarket parts or stick with origional? The only thing affecting ride hight is springs, but when you fix one side only the car should be higher no lower...Anyone have any ideas???
