Performance Friction two-piece rotors for the 2018+ WRX STI offer lighter weight and better thermal efficiency. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.
PFC's new V3 disc/hat retention system features a patented attachment design that uses a retention ring that holds the hat and disc together. The ring means no need for torque wrenches, and no hassle. The ability to change a disc quickly and efficiently saves time and effort. As well as being convenient, the new V3 technology is much lighter than previous designs, making it easier to put on and pull off, and making the vehicle lighter. The PFC two-piece rotor weighs only 15.45 pounds, compared to 23.3 pounds for the stock rotor, and over a pound lighter than the competing two-piece rotor.
V3 two-piece rotor benefits:
The hat section of the PFC rotor is made from 6061-T6 aluminum. The disc is made from a proprietary cast iron; the directional multi-vane design maximizes cooling.
Once the PFC two-piece rotor system is in place, simply replace the cast iron rotor rings when needed.
