I am ordering a set of Shelby Redline wheels for an 07 Shelby GT. I am pretty sure I need 35mm offset for the 20x8.5 front. I am not sure about the rear 20x10's. They offfer a 30mm and a 41mm offset. Which one do I need?

 

I have Steeda 18x9.5 w/275x40 on all 4 corners. The offset is 45mm with no clearance issues. Go 41mm, you should be ok.

 

The 41 is the way to go. The 30 will fit, but it will limit the tire width you can use. 30 mm on a 10" wheel is a better fit for the sn95's.

 

Thanks guys
