Note: Wheels to 5.50" wide are compatible with brake rotors that have regular 3.25" radius counter bored bolt circle mount holes and 56.3mm ID. 5.50" and wider wheels will not take stock brake rotors due to the larger (2.50" OD) wheel bearings that are used in these wheels.

For the latest information on approval see 'performancemachine.com' and search for wheel type, sizes and model application to see if a specific wheel comes with approval documents.
