Hey everyone. I'm going to do a 5 lug swap and going to need new racing rims. Right now I think the rims I have are 15x7 they might be 15x8. But is anyone running a 15x10. Also what kind of Backspacing is needed. 4.5 or 5.5

I don't have Quad shocks on my car. After market lower control arms. If I have to I will put Dumps on the car and get rid of the tail pipes. Car is not mini tubbed either.

15x10 with a 6.5" backspacing is what you need... your gonna have to roll the lip and massage the inner fender well

Ok I all ready have the Fender lips rolled. I will have to break out the 5 lb sledge hammer and give it a nice contor. Unless I just have the car mini tubbed. Which would be nicer Mabye that will be next winters project and have the interior and some other Tin work done.

Ok so a 6.5 back spacing Thanks for the info.
