hi ... i put some eibach 1 inch drop spring about 2-3 months ago and with the stock 245/50 16. it rides good but i put different wheels on the rear 255/60 15 and i just notice that the rear passenger side sags. went for a drive and it just rubs and the fender. the rear driver side is fine. might anyone know what the problem might be?

 

what is the back spacing on your rims also did it sag with the old tires ????

 

hate i hijack a thread but i was going to post the same question so i figured i would consolidate things a bit

i put on sportlines last week, car looks great, but i have the same problem, i had it with the iroc replacement springs i had before, but the car was higher and it wasn't as noticeable. my passenger side rear is about 3/8 lower that the driverside, but nothing rubs cause i have an adjustable panhard. i was wondering if a wasted shock would cause this?

 

i didnt really notice if it did with the original rims but nothing would rub

 

You need to find an adjustable panhard bar.

Due to the design of the suspension, when either raising or lowering the car the rear end will offset to one side or the other because the length of the panhard bar needs to change to keep it in line!
