PARAGON Replacement Front Rotors – Subaru WRX STI (GDB/GRB/VAB) – 4-Pot Caliper
These Paragon replacement front rotor rings suit Subaru WRX STI models with 4-pot front calipers that already run Paragon 2-piece rotors (P2R.042.326.300.18000.08.03.01/02.F). The 326 x 30mm rings are a direct replacement for worn friction rings, restoring the thermal stability and consistent braking of the original set.
Rings are cast from CM-250 high-carbon alloy, heat treated to minimise warping and vibration, and feature directional cooling vanes that cut operating temperatures by up to 30% plus a slotted face for consistent pad contact. Fresh rotor hardware is supplied so the floating assembly can be rebuilt properly.
Note: For vehicles fitted with Paragon 2-piece 326 x 30mm rotors only. Use the new hardware supplied and follow the included assembly instructions, then bed in the pads before hard use. Installation by a professional is recommended.
