Offset to Backspace Calculator
Backspace to Offset Calculator
Use this calculator to find your offset by plugging in your backspace (inch) and rim width (inch)
Offset can be positive or negative
See our fitment below as an example.
NEGATIVE offset number means the mounting flange is past the centerline of the rim towards the inside of the car.
POSITIVE offset number means the centerline of the flange is towards the outside of the rim.
ZERO offset indicates the mounting pad centerline is dead center in the rim.
