Weld Wheels Backspacing?
 
So I did the search and found that people using the Weld Wheels are using a 15x8 with a 6.5 in back spacing. There was only one person who was using the 15x10 like I want to do and his name is LUPE. I would like to know what the backspacing is for the 15x10 and if they will clear the calipers. I have the rx7.com launch kit on the car and was wondering if I could squeeze a 315 drag radial under the car without having to cut on anything? Any help would be awesome thanks.

Eric had a ford rear with totally different backspacing. BTW, you'll need a 7.5 backspacing and still will have to grind the piss out of your caliper so it won't grind.

Lupe is now Vikingwarhammer. Pm him and ask or he may chime in.

Thanks for the update ultimatejay. I saw that you have to grind off some material for clearance. Ernie do you know how much you have to grind out and is it still safe?

i run 5.5 backspacing on 15x8 and it works fine. some grinding is needed but not much.
