About this product

Part #: 81.646.9931

StopTech AeroRotor Replacement Kits ARK are designed to replace your vehicle's original factory rotors, while retaining the factory brake calipers. Although the ARK is the same diameter and thickness as the factory rotors, it offers improved cooling, braking, and handling. The directional, floating AeroRotors allow independent expansion of the rotor and hat without "coning," thanks to elongated drive pin holes. ARK components include AeroRotor friction rings with patented internal vane design, pre-assembled to billet aluminum AeroHats with directional stand-offs that optimize cooling airflow. The patented AeroRotor vane design pushes up to 80 percent more air than factory rotors for better cooling and reduced fade on the track. The aircraft-grade aluminum hats and 2-piece AeroRotors are up to 8 pounds lighter than stock rotors, allowing faster acceleration and deceleration, and improved handling. StopTech AeroRotors are available slotted or cross-drilled. These slots or holes allow better dissipation of heat, friction material and debris, assuring that fresh pad material is in contact with the rotor every time the brakes are applied. An optional anti-corrosion, zinc finish is available for customers in cold climates, where salt and chemicals are used to melt snow and ice. The zinc coating also benefits customers who prefer no visible surface rust on the vanes and outer circumference of the rotors. StopTech AeroRotors are 100 percent made in the USA.

What made you choose this particular product?
Past experience. They're really quiet (unless they're crazy hot), have really good fade resistance, and good linear bite regardless of temperature. Price is also really hard to top for performance pads.
Is this your first time buying from this brand? Did you consider other brands?
No, I've run them on my tc and my old mr2. Not really, I'm pretty dead set on these pads.
Was it easy to install? Any installation tips that will help others?
Like any other brake job.
Once you've had a chance to use the product, did it meet your expectations?
Yup, I already know what to expect from them.

Based on reviews, these were the best rotors to go with without stepping up to a BBK.
Is this your first time buying from this brand? Did you consider other brands?
This my second time purchasing from StopTech. I have used their pads in the past.
Was it easy to install? Any installation tips that will help others?
Very easy to install.
