If you're ordering Weld RTS wheels, then 15x10 4.5" backspace is what you'll need out back, and 15x3.5 with 1.50" backspace is what you will need up front. Same with the rears with Prostars..however with Prostar fronts you can use a 1.75" backspace, but they won't fit over your OEM LS1 brakes, so you'll have to use a spacer, which will make them sit at about 1.5" anyways!

in saving for weld rts
18x9.5
18x11
I know the rear offset
just need fronts. if I put 1"
adapter my current fronts
will have a +28m offset so
theoreticaly a 18x9.5 with a
+30 would be fine right

9" rear narrowed 3" per side, Weld RT-S 15x10 with 5.5" backspacing and 295/55/15 M/T ET Street Drag Radials if you want the wheels to tuck under the fender.
