Big Brake Caliper and Wheel Clearance

Most 13" big brake kits require 17" or larger wheels, with at least 50mm of clearance to the back of the spokes: see the drawing below. The Konig Villain rim (17x9) provides adequate caliper clearance for 13" big brake kits from StopTech, Brembo, and Wilwood.

Big brake kits with 14" rotors require 18" or larger wheels.

For the most accurate information about the clearance requirements of big brake kits, always check the manufacturers own website for drawings and templates. See below for links to StopTech.

If you are using a wheel that does not provide adequate spoke clearance, sometimes wheel spacers can be used to increase the distance between the back of the wheel spokes and the caliper.
