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.
