Please help a fella in need. I want to order a set of 15" Cragar Drag Lites for my 89 Firebird but I have no idea what backspacing or width or bolt pattern that I need. I really want a 10 inch wide rim but I dont know if it will fit (I dont want them to stick outside of the fender wells). What is the widest rim that I can get inside of my 89's fender well and what backspacing will I need? I also want a 7 inch rim up front so what backspacing up there?

THANKS IN ADVANCE

 

bc is 5 x 4.75
bs should be 4.5

Does anyone else have any information on the wheel specifications???

 

we have them on my wifes car (the 82 Z28 in my sig) they are 15 X 7's with a 4.5 back spacing. the bolt pattern that you need is 5 X 4.75.

 

My 15X9 warriors stick out of the wheel well about a half inch, If you have drum rear brakes 4.5in back spacing is the most I could go, 5in rubbed. Disc brakes you should let you go 5in but no guarantees. I would say there is no way you will get 10in rims to fit entirely in the wheel well, 9's maybe, 8's definately.
