This is the replacement 380X34mm Stoptech Aero-Rotor for the front right. These are typically found in Stoptech’s BBK kits, and are available separately for those of you who need a replacement.
Stoptech designed their AeroRotors to allow independent expansion of both the rotor and hat without “coning”. This is accomplished with drive pin holes. The AeroRotor also contains billet aluminum Areohats with directional stand offs that promote better cooling.
The AeroRotors are up to 8lbs lighter than stock rotors, allowing for less rotational mass, increased acceleration, deceleration, and improved handling. These particular AeroRotors are slotted which creates a “swipe” action that repels heat gases and brake dust on extreme conditions. This means that you will have a cleaner friction surface, and a cooler running rotor.
Stoptech rotors are 100% made in the USA.
