I am mounting 15x10 prostars in a collector edition ramair 02. front 15x3.5 . I grinded the hell out of the front calipers and they worked know thwe back i was i told i didn't have to but my are hitting bad. Does anyone have a similar setup. Any tips.

 

I hear 7" backspacing is required, but they supposedly still need grinding.

Anyone?? Also do a search there seem to be a lot of questions in regards to this.

 

Not sure of what backspacing you have. But I had to grind and use a spacer. I also used extended studs as well. Only way to be safe with the spacer. The spacer is 5/16 ths. Dont know where you get them. Mine were custom turned on a lathe.

 

You need a 7.5" Back Spacing. I was going to throw Drag Lites on my car, but either way, i would still have to grind down my calipers and thats not going to happen.
