I have had some serious problems with my wheels rubbing and I need help. Here's the story... I've had 17x11 zr1's in the rear for a few years with no problems. I lowered my car last year and installed some LCA and relocation brackets with no problems. Ever since I changed my wheel bearings and bottomed out my wheels have been grinding against my bump stops. So after cutting my bump stops off, adding a adj panhard bar, adding an air lift, and beating the fender wells they still rub. I noticed that it was mostly my passenger side that was rubbing and after adjusting the panhard bar its rubbing the driver side. My rear end seems to be centered and it doesn't always rub. I don't think that my axle tubes are bent either. I'm really stuck and don't know what to do. Any help would be greatly appreciated.

If you have poly ends on your aftermarket suspenion and its not rubbing all the time then it might be your poly ends flexing. I replace the ones on mine with Derlin bushings.
