Does anyone know the correct backspacing on a weld pro star xp, 15/10, and 15/8?? This is for my 98 cobra, Thanks,

John.

I have a regular prostar, not the xp on my 94gt and I used a 15 x 10 with a 6.5" backspace. It comes pretty close on the inside but nothing rubs. Thats with a 275/50/15 bfg drag radial.
Will the xp's fit over your brakes in a 15 inch?
