Hey guys, Im going to throw on some cragar soft 8s. 15x10 rear and 17x8 front. I know they are kind of heavy but trying to keep my truck semi low-key.

can someone help me with the exact backspacing i need for our truck with these wheels? its a 07 silverado.

I want to run a et street radial 295/65r15 on the rear
Probably run a 235/65r17 front tire.

Also, want to spin a d1 pretty heavy but not to its limit. will be on e85. what # boost you recommend and the pulley size to get it? would like to get 700-750 WHP

thanks!

 

6.5-7" is what most run on backspacing. The smaller the backspacing the more the wheel will stick out past the bed
