Fitment & Compatibility
Measure bracket offset and rotor diameter together. The compatible 7816/7216 pad shape helps define the swept area, while the piston sizing must agree with the master cylinder and opposite axle.
PMB Performance has worked with brake components for over 20 years. Share the required piston sizing, rotor measurements and bracket drawing for help checking the match.
