BMW F-Series M2 / M3 / M4 — Front Replacement Rotor (380x30mm)

Two-Piece Floating Rotor | THERMACORE™ Alloy | Track Ready

Engineered as a direct front replacement for the BMW F-Series M2, M3, and M4, our 380x30mm two-piece rotor is built to outperform the OEM disc in every category that matters — heat management, consistency, weight, and long-term serviceability.

Whether you're carving up canyon roads or chasing lap times on track, this rotor is designed to take the beating and keep delivering the same pedal feel from your first lap to your last.


Why This Rotor

THERMACORE™ Treated Alloy
Our proprietary THERMACORE™ treatment increases the rotor's resistance to heat soak, thermal cracking, and pad fade under repeated high-load braking. The result is a friction ring that stays composed when conditions turn extreme.

Two-Piece Floating Construction
A forged aluminium centre hat is paired with a high-grade iron friction ring via floating bobbin hardware. This allows the ring to expand and contract freely with temperature — eliminating stress build-up, warping, and the dreaded pedal pulsation that plagues single-piece OEM discs.

Rebuildable Design
When the friction ring reaches the end of its service life, you don't replace the entire rotor — just the ring. Lower long-term cost of ownership without compromising performance.

Reduced Rotating Mass
Lighter than the OEM cast disc, reducing unsprung and rotational weight for sharper turn-in, faster acceleration, and less strain on suspension components.


Choose Your Slot Pattern

Three slot geometries — each with its own character. Pick the one that suits your driving style.

  • J-Hook — Aggressive and track-focused. Maximum pad bite and gas evacuation for drivers who push hard.
  • Curved Slot — Smooth and consistent. Excellent all-round performance with quieter operation for street and light track use.
  • TY — Balanced pattern designed for progressive bite and even pad wear. The all-rounder.

Choose Your Hat Colour

Forged aluminium centre hat finished in hard anodising — a process that penetrates the aluminium surface for a significantly harder, more corrosion-resistant, and longer-lasting finish than standard anodising.

  • Black — Stealth, understated, OEM-plus aesthetic.
  • Bronze — Warm, premium accent that pops through the spokes.
