backspacing for 15x8 and 15x10 rallyes?
 

im going to be ordering some new vette/camaro style rallye wheels in 15x8 and 15x10. What backspacing do i need to keep the outter edge of the wheel near the lip of the wheel wheel. The stock wheels now are tucked WAY to far in.

also what are the widest meats i can fit on these front and rear.

I would run 4" front and 4 1/2" rear....that should push them out nicely but not past the wheel well lip.

sounds good, what should i run for tire sizes (bfgoodrich radial t/a's)

If you ever want to bag or lower it drastically go with 4 1/2 and 5 inches in the back.
