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.

BMW E46 M3 & 3 Series E36 3 Series Front Installation Instructions
Most 17” wheels will clear the outer diameter of the caliper for a 328mm or 332mm rotor kit. For a 355mm kit, a minimum 18” wheel is typically required, and for a 380mm rotor kit, a minimum 19” wheel is needed. The more critical clearance, however, is the gap between the spokes of the wheel and the face of the caliper. Do not assume that a larger-diameter wheel will automatically clear the face of the caliper.
To determine the actual metal-to-metal distance from the stock rotor face to the inside of the wheel spokes, refer to the StopTech website at www.stoptech.com, and click on the ‘Wheel Fitment Charts’ link at the bottom of the home page. BEFORE printing out a copy of the wheel fitment drawing for your vehicle, click on the ‘How do I use the charts?’ link at the top of the page, and review the instructions carefully, to ensure that you have a full understanding of how to accurately measure the critical wheel clearances. Only then should you click on the link for your vehicle, and print out the appropriate wheel fitment drawing, to use as a measurement template.
It is very important that you verify the accuracy of the scale of the printout by matching both a width and length dimension on your vehicle. Dimensions are shown in millimeters, but one dimension in each direction is also shown in inches, and StopTech recommends adding at least 2mm of additional clearance to these dimensions. Follow the instructions carefully, to produce a fitment template, and take care to ensure that your measurements are very precise. If you have any questions or difficulties, please contact the StopTech Customer Service Department on (310) 325-4799 - extension 105, or send an e-mail to support@stoptech.com.

2000+ BMW X5 Front Installation Instructions
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.
