For best calliper clearance, the rule of thumb is to take your rotor diameter in inches + add 4 extra inches.

Example:

• 328mm rotor (12.9") - minimum 17" wheel
• 332mm rotor (13.1") - minimum 17" wheel
• 355mm rotor (14") - minimum 18" wheel
• 380mm rotor (15") - minimum 19" wheel

It's crucial to check the vehicle and the parts on the vehicle to make sure that the brakes will fit.

Space for the calipers varies by wheel design. Two wheels with the same offset, same diameter, and same width will yield two different fitments. One that does fit over the brakes, and one that does not.
