Caliper Clearance

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

.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 di-

mension 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 ques-

tions or difficulties, please contact the StopTech Customer Service Department on (310) 325-4799 -

extension 105, or send an e-mail to

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.

Many wheel-cleaning solutions contain strong acids that may damage the finish on any caliper or

aluminum anodized finish, especially the plating on the hardware. Check for adverse effects by

trying a small amount of the cleaner in question on an inconspicuous area. Avoid over-spraying,

and rinse cleaning solutions off as quickly as possible. StopTech is not liable for damage to calipers,

hats or bracket finishes, due to corrosive chemical exposure.
