ok ive looked for the thread about wheel backspacing and what not but i couldnt find it.anyways on my 07 cc below how far would a wheel with 4.75" backspace and -6mm offset stick out?? and also hub sentric on non hub sentric?

What is the width of the wheel in question? And always go with hub centric wheels if you can. It'll make for a more secure mounting point on the wheel's hub and not require the use of hub rings.

You're looking at setting the rims 2.45" further out past the fender wells compared to stock. If that's your thing then go for it but I don't think it'll look very good.

I believe 17x7 with 5.2" of backspacing. I usually deal in backspacing measurements because it's something easy that I grew up with so if you want the offset of stock rims just wait till tomorrow and I'll look up the specs at work. I work for Discount Tire here in MN and have been in the tire and wheel business for 5 years now. It's become a sickness but at least I'm good at it after so long!

I didn't believe it when I read it at first but after doing the quick math is seems right...Stock 17x7 GM rims have +43.18mm of positive offset. I thought it was around +35mm but who cares really I hate using offset. Backspacing was drilled into my head when I was young by both my grandfathers and using offset, to me at least, is like trading in my big truck for a souped up Civic. Plus, my tape measure measures in inches, not millimeters so quite frankly, **** offset. haha

ok with that info the backspace on a factory 17x7 is like 2".so adding another 2.75" prob wouldnt to bad imo.im gona put a tape measure to the truck tommorrow and see how far they stick out. thanks inchup
