17x11"s making noise after modifying f-wells?

I just put the ZR-1 style 17x11's on my car wrapped in 315's. I had the bump stops completely removed and cut off the "inner-fenderwell" and beat in parts of the outter fender-well where it looked like it may rub. On the car lift it looked like i had plenty of room. Well i drove the car yesterday and when i make HARD turns the rear makes a "sqeaking/squealing" noise when the car body rolls. If i make a hard right turn it sqeals on the left. I cannot see where the tires are rubbing if they are at all. Could it be a noise with my actual rear-end after putting bigger tires/wheels on. I'm clueless because i can't see where they could possibly be rubbing at. When i drive normally there's no noise at all only under hard turns. ANY HELP!?!?!?!?!???

You're going to have to find where its rubbing. Excessive body roll - as on a drag car with the front sway bar removed - will cause major rubbing problems. Weak bushings in the panhard rod would also let the body shift from side to side under hard cornering loads.

Have you taken the wheels off to see if you can spot any rubbing spots? That's what I would try next. :dunno:
