i have a 85 firebird and i have c5 zo6 rims the backs are 18x9.5 iv herd that the 4thgen rearends push it out enough so the rims can fit mine do fit but there about a 1/4 of and INCH close to the body of the car thats without the tires on it i haven't bought the tires yet. i know others have done what im doing but do they really fit with no tire rub or anything becaus it looks so close to the body i don't see how they are gona work, or is the 1/4 just enought so it doesn't rub, do i need spacers maby?

If pictures are needed to help explane let me know i can get some thankyou.
