The dust shield must be permanently removed from both rear wheels of the vehicle, to accommodate
the AeroRotors. This involves cutting each shield with sheet metal snips or a power cut-off wheel, and
de-burring sharp edges with a file or power die grinder. These operations can be dangerous, and
serious injury can occur. For anyone who is not competent or comfortable performing these opera-
tions, StopTech firmly recommends that they seek the services of a trained professional. Proper pre-
cautions, such as safety glasses and work gloves, will be required.

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. The actual metal-to-metal distance, measured from the stock rotor face to the inside of the
wheel spokes, is 65.40mm for the 2000+ BMW E39 M5 and 5-Series rear kit. StopTech recommends at
least 2mm of additional clearance.

The most common cause of brake vibration is improper bed-in of pads and rotors, or improper pad
selection for the specific driving environment. Rotor run-out may also cause vibration, but precision
manufacturing and inspection typically mean that run-out is not an issue. Modern production meth-
ods ensure that the rotor run-out is within +/- 0.002” when installed on a StopTech aluminum hat,
and it controls thickness variation to within 0.0003”. Under the most extreme conditions, any rotor
may warp, but uneven pad deposition is a more typical cause of vibration. If the system is not
properly bedded-in, or if street pads are run on an open track, uneven pad deposits will occur, caus-
ing 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 procedure
included in this manual. If you have any questions, please contact the StopTech Customer Service
Department on (310) 325-4799 - extension 105, or you can e-mail directly to
