About this product

Part #: 81.334.9931

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?
I tried to have my slotted rotors machined, but it was too warped that braking caused severe vibration reverberating through to the brake pedal. Not Good. I needed a cheap replacement ASAP.
Is this your first time buying from this brand? Did you consider other brands?
No. I had the slotted rotors, but I tried to save money by just buying pads. Not a wise choice.
Was it easy to install? Any installation tips that will help others?
If you can turn a bolt, you can install this part.
Once you've had a chance to use the product, did it meet your expectations?
Definitely a good rotor.

What made you choose this particular product?
The performance and the fact that it worked with my vehicle
Is this your first time buying from this brand? Did you consider other brands?
First time buying from this brand. This consider the Motul as well.
Was it easy to install? Any installation tips that will help others?
Very easy. Take old fluid out of reservoir with a turkey baster and then put new fluid in and do the proper fluid flush through the brakes. Helps if you're doing lines at the same time.
Once you've had a chance to use the product, did it meet your expectations?
So far so good.
Any additional comments?
None.

What made you choose this particular product?
Once again, input from the forums that these pads were better than the alternatives.
Is this your first time buying from this brand? Did you consider other brands?
Yes. I had my heart set on EBC Redstuff pads, but thankfully the forums convinced me otherwise.
Was it easy to install? Any installation tips that will help others?
Pads were an easy job, rotors not so much.
Once you've had a chance to use the product, did it meet your expectations?
Exceeded them completely. The car stops much better than stock, and dust levels have greatly decreased.
