About this product

Part #: 81.344.9911

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?
This part was installed on my 1998 BMW M3 when I purchased the car. They work pretty good and can handle the hard use required for track days.
Is this your first time buying from this brand? Did you consider other brands?
I considered Brembo brakes, but I already had the StopTech BBK, so it was a no brainer to just clean them up and re-use them.
Was it easy to install? Any installation tips that will help others?
Installation was pretty straightforward. I mean if you can install a regular set of brakes, you should have no issues installation these. I would say that you should be aware of possible fitment issues with your wheels. These calipers are much larger than stock calipers and may not fit with OEM wheels (my OEM M3 wheels did not fit with these brakes). Even aftermarket wheels might require spacers.
Once you've had a chance to use the product, did it meet your expectations?
Good brakes, but rotors are pricey. Replacement rotors cost about $700 a pair, or $1,100 if you order them with a new set of rotor hats.
Any additional comments?
One other issue, I noticed galling on the M12 bolts that hold the StopTech carrier to the wheel hub. I ordered an M12 x 1.5 TimeSert kit to repair the threads in the aluminum carriers. It seems to me that StopTech should have manufactured an aluminum carrier with thread inserts, out-of-the-box, to avoid this issue.

What made you choose this particular product?
I love the way the 335i comes to a seemlessly smooth stop from any speed. Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. Cross-drilling a rotor is a way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder
