Wheel Back Spacing Info

Rim Width / 2 = Centerline
Centerline + Offset + Rim Lip = Backspacing

8" wide rims / 2 = 4" Centerline
4" centerline + 0.63" Offset + 0.35" Lip = 4.98" Backspacing

Adapters
Adapters move the rim further out. They let you bolt on rims with too much backspacing. If you decide you want to
bolt on a pair of Corvette ZR1 rims (17x9.5", 50mm Offset) you would first need to calculate the backspacing.

9.5" / 2 + 50mm / 25.4 Offset + 0.35" Lip= 7.07" Backspacing

Rim Backspacing - Max Backspacing = Adapter Thickness

7.07" - 4.95" = 2.12" Front Adapter Necessary
7.07" - 5.85" = 1.22" Rear Adapter Necessary

Ideally, you would want some clearance on the inside of the rim to compensate for suspension movement, etc. In
this case, we recommend 2.25" adapters for the front and 1.25" adapters for the rear.

Offset
Offset is the distance from the rim's mounting surface to the centerline.  Positive offset means the mounting
surface is moved towards the outside (away from the center of the car) of the rim. Negative offset is the opposite.
