Ok guys, i ordered a set of Intro Pentia wheels. I ordered 18x10"s with 5.5" backspace for the rear, 18x8 with a 4.75" backspace for the front and an extra set of 15x10's with 5.5" backspace for my drag radials. My question is, do any of you run this backspace??? I have read that people fit this without notching the frame but I dont see how it is going to work. I plan to notch the frame so that will help. i will also be running F-body discs in the rear which will bring the wheel out 3/8 of an inch. What tire sizes are you guys running with this backspace??? Thanks! -----Jeremy
