my fellow firebird people: i must admit i am a novice when it comes to the rebuilding of my car and i made an error with the purchase of my rims and tires and i need help correcting it. i now have on the rear 17*9.5 rims with a 5 inch back space with Kumho ECSTA SPT ttires with a 275-40-17 tire. the problem is i got the tires on back out of the drive way and the chasis locked into the tire, causing minor fender issues in the inner wall. what can i do to get the clearence i need? it looks like the multi leaf springs are original and and the shocks are 3-4 years old but sat with one flat rear tire for a year. anything i can do to not raise the rear end or is it going to have to be the case. any help guys would be great. thanks.
