I'm trying to figure out what wheel spacers I'm going to need for the rims I have. I went with 17x9 in the front and 17x10.5 in the rear. If someone has used this wheel setup before on A&C kits, what backspacing number did you use in figuring out the thickness of the wheel spacer? I have searched this form and found people who used taller and wider rims went with a 4.5" backspacing for the front and the rear. Thanks for the help.
