I searched and only got confused. What is the actual lug pattern on my 91 gta? Im looking to get some centerline telstars and also need to know what offset i need? Im looking to get 15x10 in the rear and 15x4 or 15x6 in front.. Any help would be greatly appreciated..

 

all fbodies use 5x4.75 lug pattern...i'm not sure what the backspacing is though

 

does anyone know the backspacing i need if i purchase 5x10's?

 

I dont know the answer to the 10" wide wheel offhand, but you can find it if you search. There was recently a thread about this in these forums with specs and pictures, I know it had the infor for 10" wide. But for the front wheels, I dont remember seeing those specs for 4" and 6" wide in any of the threads I've read. On that one I would find the specs of wheels with the same widths being sold by a manufacturer specifically for 3rd gens and then copy the specs of their wheel and apply it to yours. I know a few guys have done it that way but dont remember them posting what the results were.

 

5.5 bs on 10 inch is perfect fit on a third gen rear with a 275 50 15 tire it set right even with the fender lip. there are pics on a recent thread . 15x4 or 15 x6 i dont thint bs matters as much cause the are so narrow
