AeroRotors
StopTech AeroRotors are patented 2-piece hat and rotor
assemblies designed to replace original factory rotors while
working with the factory brake calipers. Each StopTech AeroRotor
Kit contains a pair of AeroRotors to fit the front or rear axle of
your vehicle. Although the AeroRotors are a direct replacement for
factory rotors, StopTech AeroRotors offer significantly improved
cooling and overall braking performance thanks to several design
enhancements and patented innovations.
The 2-piece directional, floating AeroRotors are specifically
designed to allow independent expansion of the rotor and hat
without coning thanks to elongated drive pin holes. Available in
MAX-float for racing, or controlled float for quiet
street use, AeroRotor components include an AeroRotor friction ring
with a patented AeroVane design and pre-assembled directional
billet aluminium AeroHat with carefully engineered directional
stand-offs to optimize cooling airflow. The panted AeroVane design
pushes up to 61% more air for better cooling and reduced fade on
the track.
By using lightweight aircraft-grade aluminum for the hats, the
2-piece AeroRotors are up to 8 pounds lighter than stock rotors.
The lighter rotational weight allows for faster acceleration and
deceleration, and nimbler handling.
StopTech AeroRotors are available in slotted or cross-drilled
finish. Slots and holes allow better dissipation of heat, friction
material and debris assuring fresh pad material is in contact with
the rotor face every time.
An optional anti-corrosion gold zinc coating benefits customers
who live in cold climates, where snow and road salt are commonly
encountered. Zinc coating also benefits customers who prefer no
visible surface rust on the vanes and outer circumference of
rotors.
StopTech AeroRotors are 100% made in the USA, with
both casting and machining taking place in California.
StopTech AeroRotor Rings
The patented 2-piece AeroRotor assembly uses uniquely designed and
patented AeroVanes inside the disc to optimize airflow through the
rotor. This improved directional design minimizes turbulence and
flows up to 61 percent more air than any other rotor tested. The
result is up to 80 percent better airflow over original equipment
rotors and 10-30 percent better airflow than other directional vane
racing rotors currently available. Better airflow equals better
cooling, and better cooling means less fade and better overall
brake system performance.
StopTech AeroRotors also feature a proprietary alloy chemistry.
By adding molybdenum to the gray iron, carefully targeting a narrow
range of hardness and tensile strength values, and controlling the
cooling rate of the rotor after casting, StopTech produces a
friction ring with added crack resistance as well as improved
functionality.
Drive Pins
In certain applications where packaging is an issue such as on the
Chevrolet Corvette StopTech uses slant-head drive pins to provide
improved clearance as pads wear.
Zinc Plating
Zinc Plating, available on StopTech AeroRotors, prevents corrosion.
This is particularly useful in winter climates where road salt and
other environmental factors may increase the likelihood of
oxidation.
