Increase the braking, handling and brake cooling of your Volvo C30/C70 and S40/V50 by installing a set of Stoptech 2-Piece AeroRotors.
Stoptech 2-Piece AeroRotors are designed to be direct replacement rotors for your Volvo C30/C70 and S40/V50 that are equipped with 320mm size front brake rotors. These 2-Piece rotor feature the same factory dimensions while providing better cooling, handling and improved braking. Patented AeroRotor vane design pushes up to 80% more air than factory one piece rotors. This allows for proper cooling and reduced brake fade under hard braking.
These Rotor are available in Slotted or Drilled patterns with an optional Zinc coating. The Zinc coating helps aid in corrosion protection for longer lasting brake rotors.
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.
Super strong Inconel® drive pin washers - as used in aircraft engines and other racing applications - are practically impervious to oxidation or corrosion even at extreme temperatures.
Street rotors use a curved drive pin washer to add tension to the hat assembly, reducing rattle. Race applications use a flat washer that allows full freedom of movement between hat and friction ring.
StopTech AeroHats feature directional stand offs to further improve airflow and cool the rotor.
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.

StopTech Sport Slotted Rotors are priced and sold individually on our website.
* While the required rotor diameter can be determined based on your VIN number, many cars now have different sized rotors fitted by mechanics than what the car was originally fitted with. As such, we advise that you physically measure the brake rotor diameter to determine your correct rotor size prior to ordering.
