I'm looking at puting some Cragar SS rims on my 78 Z28. I'd like 15x7 in the front and 15x10 in the back. Can anyone give me the measurements I need (bolt pattern spacing, back spacing, etc) Thanks

 

Do a search on the forum as this has been posted a couple of times. I'm at work otherwise I'd post some links. At home I have a link to an online database of what types of combinations (tire sizes, backspacing, etc.) users have tried. I'll see if I can remember to post a link later on tonight. I think a 3 - 3.5 inch backspacing is stock for the z28 rims but I can't remember 100% so don't quote me.
