Track-day-ready rear brake upgrade for the BMW M3 E46 (2000-2006). No fluff, no guesswork: Paragon PA025 4-piston calipers and 355x32mm fully floating two-piece rotors with 48 directional vanes.
Hard-anodised calipers and rotor hats - built to resist discolouration and wear on fast road or circuit use
Up to 30% cooler running than OE - consistent bite and modulation after repeated hard stops
Fully compatible with stock ABS and master cylinder - no modifications required
No OEM parking brake function - intended for track-focused builds, not daily drivers needing handbrake operation
