Product Details

AeroRotor™ 2-Piece Replacement Rotor Ring by StopTech®. Quantity: 1 Per Pack. StopTech has developed several design innovations to improve rotor airflow. The patented 2-piece AeroRotors push more air thanks to curved, airfoil-shaped vanes and an air channel that widens at the trailing edge of the vanes.

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.

Well Learning Experience...
Well brought these and their street performance pads for my 2013 ford f150 FX4. Well in my personal use they didn't fit my calipers so I will have to buy a new set of those as well, so if you are getting these for your F150, you might want to either get new calipers as well or get different rotors.

Performance Brake Rotors
Great rotors. Haven't been able to really try them out for autocross yet, but daily driving has been great, paired with the StopTech pads not a lot of dust.

Won't Last a Week.
Replaced these on my Camaro SS, heat cycled them like they said to do with the new ceramic pads. They were warped in less then 2 weeks. Need a better warranty than 60 days. Performance Brake has a lifetime warranty, is what I will be going to.

Nice Product
Good product, nice packaging, very easy to install. The holes should be flush, the edge gets rust when it get wet so the pad is unable to remove it when braking.

Passenger Side Front Rotor
From the unboxing, all looked normal. Up to the point that I put the rotor on the hub, 2 of the 5 lug holes were misaligned by 2 millimeters. Not enough to prevent the rotor from seating on the hub, but definitely noticeable once the rotor was on. Then I tried to attach the rotor to the hub with the set screw only to find that the hole was not drilled/milled into this particular rotor. Disturbing and aggravating considering how easily the drivers side rotor went on the hub with no issues. At this point, I couldn't wait a week for a replacement rotor nor could I put the 13 year old OEM rotor back on the vehicle. When I order the rear rotors, I will be checking them both before I start any work on my car.

Driver Side Rotor
Excellent fit, aligned perfectly, went on smoothly with no problem, all lug holes and set screw hole were drilled and lined up correctly. Reassembly of the driver side front end took roughly 20 minutes from unboxing the rotor to mounting the wheel, not including bleeding the brakes.
