Most 18” wheels will clear the outer diameter of the caliper on a 355mm kit. However, the more critical clearance is the gap between the spokes of the wheel and the face of the caliper. Do not assume that a 19”, 20” or even 24” wheel will clear the face of the caliper. The actual metal-to-metal distance measured from the stock rotor face to the inside of the wheel spokes is 62.25mm for the BMW X5 front kit. StopTech recommends at least 2mm of additional clearance. See the Wheel Fitment Drawing page on the StopTech website for more specific measurements, at www.stoptech.com. Note: Final fitment of the wheel to the caliper is the responsibility of the customer.
Wheel Spacers
Wheel spacers can provide extra clearance to the outer face of the caliper. This will also space out the entire wheel, widening the track width of the vehicle. Fender clearances should be checked on lowered cars, and longer lug studs or wheel bolts are usually required. Note: The Wheel Industry Council has issued guidelines advising that wheel spacers not be used. It is the responsibility of the customer to ensure that wheel spacers are properly specified and installed.
