Can any one tell me what the off set on my car is i have a 1987 trans am and will it be the same as a 1989 gta ?

 

Gta rims should bolt up no problem . Im not sure of the exact offset of your car though but the basic chasis design will be the same

 

Not sure what the exact offset is but I know on my '87 IROC the front and rear offset were different.

 

dammit, i told you on msn how to find it!!! dont be lazy, get to it! lol

 

hahaha
lazy kids

 

Both the cars take the same fitment.You may notice there is a front & rear backspacing diff. on these fact wheels[fronts have more backspacing]For a 7" wheel you want about 4.5" backspace.Ona 8" wheel 5" backspacing.you can go 9.5 rear with 5.5-6" backing.I worked with an importer of custom wheels for years and was a tech guy for all of Canada[in case your ? my thred reply]Hope this helps.
