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 a 19, 20 or even 24 inch wheel will clear the face of the caliper.

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 wheel spacers not be used.

Brake Vibration - THIS IS IMPORTANT!

The most common cause of brake vibration is improper bedding of pads and rotors or improper

pad selection for the specific driving environment. Rotor runout may also cause vibration, but

precision manufacturing and inspection typically means runout is not an issue. Double disc grind-

ing insures the rotor runout is within +/- 0.002” when installed on our aluminum hat and controls

thickness variation within 0.0003”. Under the most extreme conditions, any rotor may warp, but

uneven pad deposition is a more typical vibration cause. If the system is not properly bedded in, or

street pads are run on an open track, uneven pad deposits will occur causing an ever worsening

vibration. Failure to immediately address a pad deposition/vibration issue may lead to permanent

damage of the rotors. Please read and understand the bed-in procedures included with this manual.

If you have any questions, please contact the StopTech Customer Service Department for assistance.

Brake Noise

Certain brake pad compounds make more noise than others. Proper anti-squeal shim plates be-

tween the caliper pistons and backing plate of the pad help reduce the problem. Anti-squeal lubri-

cants are also available to reduce some of the noise. The reality is, performance pads are more prone

to brake squeal.
