backspacing

[badta14]

what would be the right back spacing for welds prostars or summit warrior R/T for fronts and backs??

If you're going for 15x8's, you'll want 5.5" backspacing for the rears. 15x10's, you'll want a 7.5" backspacing. For fronts most people I believe go 3.5". You may have to grind the edges of your calipers to make sure they don't rub, although LT1's don't have that problem as much as LS1's due to their larger brakes. You can typically get away with using spacers on the fronts, but you'll need longer studs.

iv got summit warrior 15x4 that i use on the front of my 95 and they dont rub, no spacer and iv never done any grinding. and the summit warrior dont come in a 15x10 with a 7.5 back space last i looked, so ya would need a 15x8 with 5.5 for them. but the pro stars will fit with no grinding in 15x10 7.5 bs, i run then in the rears.
