Ryan Tuerck has a new Formula Drift sponsor for his Scion FR-S that was brought on right before Seattle. The company is Disc Brakes Australia and Tuerck has opted to run the 4000 series one-piece rotors. The T3 slotted brake rotor is the most aggressive one piece rotor which is optimal for motorsports applications. Good news for you street car fans is the rotor also cuts the mustard on the street. The rotors are crafted with high-carbon iron and cured with a patented process that reduces metal stress, rotor edges feature 3 paint marks which change color to reflect different levels of metal temperature, and DBA’s patented Kangaroo Paw ventilation comprised of 144 pillars between the rotor faces providing faster cooling and greater strength.
