Most 17” wheels will clear the outer diameter of the caliper. Wheel weights mounted on the inside of the wheel may need to be repositioned. The more critical clearance is the spokes of the wheel to the outer face of the caliper. Do not assume an 18, 19 or even 20 inch wheel will clear the outer face of the caliper. A minimum distance of 60.81mm, measured from the outer rotor face to the inside face of the wheel spokes. This is the net metal-to-metal measurement. We recommend at least 2mm additional clearance to clear the ST-40 caliper on our big brake kits. Please refer to the Wheel Fitment section of our website to confirm any wheel fitment issues.
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. Basic suspension settings will generally not be adversely affected by a slight widening (up to 3mm per side) of the track. Fender clearances should be checked on lowered cars, and longer lug studs or wheel bolts may be required. It is the responsibility of the customer to insure wheel spacers are properly specified and installed.
Brake Vibration
The most common causes of brake vibration are run-out and thickness variations on the rotor. Double disc grinding insures the rotor run-out is within +/- 0.002” when installed on our aluminum hat. Thickness variation is within 0.0003”. Under the most extreme conditions, any rotor may warp. Thickness variation will never change, though pad material may get deposited on one spot of the rotor if a foot is left on the brake pedal after coming to a complete stop when the system is hot. This deposited material will induce a vibration, and if sever enough, can only be cured by replacing the rotor. Not following proper break-in procedures for the rotor and pads may also cause pad deposits on the rotor. STOPTECH is not liable for vibrations caused by extreme usage or improper break-in procedures.
