ive had bf goodrich 255/70's on 15x8 with 5.5" backspace on the rear since december, i've had no problems except that the tires sometimes rub the exhaust when i turn a corner, until recently, the tires are real tight fitting in the wheel well but there is at least a half inch between the tire and the frame. but sometimes when i take off from a dead stop the car starts jerking because they are rubbing the frame. this just started happening the other day, and everytime i crawl up under it there is always enough room between tire and frame. i even try rocking the car back and forth to try to get the tire to touch the frame but never can. i have new air shocks on it and i thought they may have lost some air but after checking they seem fine. this mostly seems to happen on level ground moving straight when i take off. do they make some sort of spacer i can put behind the wheel to bring it out? i've got more room to work with towards the outside of the wheel well. is it a coil spring problem? any ideas would be appreciated. thanks.

Try adding some weight to the trunk and then take a look at your clearance.When you accelerate the rear of the car is lower and that is probably where your clearance changes.Yes you can buy "disc brake spacers" for 1/4 " or so.Actually you can buy "adapters" that will space you out 1", but I wouldn't trust them under racing conditions.

if you have only one air valve and park on an incline your car will stay level and "lean" towards the uphill tire. if you have one air valve for each shock then you have other problems.

it's only one air valve. i dont race the car in fact i baby it. the problem occurs in just about any condition (level pavement, incline or whatever) and im not giving it enough gas when i do take off for the rear to come down, in fact most of the time i notice it when i let my foot off the brake and the car starts to move at idle. one thing i failed to mention before is that i did recently have the wheel bearing replaced on the side that is giving me the problem. if i could get like a 1/4" spacer behind my wheel i believe that would take care of it but i have drums, will the disc brake spacer work?

Check your rear control arm bushings and track bar. If the bushings go out on the track bar, it will allow the rear end housing to move side to side without much effort.

If these are OK, a small spacer will be safe to use.

I used the 5/16 spacers on my ride. (66 Impala) I run 235/18/50's. I used spacers in the front and back.......The only thing you might have to do is change out the lug studs. Or get a special type of lug nut that is made for using spacers.....

if you decide you need spacers,summit has them. they are made by mr gasket & are avaialible in 7/32,5/16,7/16 thicknesses. maybe your local parts house has them. they sell for 10 to 12 bucks a pair. hope this helps.

corvettes have a spacer that goes over the tire studs behind the rim
