Track-tested construction ensures reliable stopping power for street and circuit use.
Key Features
- Two-Piece Design: 6061-T6 aircraft-grade aluminum hats with high-carbon steel friction rings reduce rotating mass by over 40% compared to OEM for sharper handling and quicker acceleration.
- Curved Slot Pattern: Precision slots expel brake gases dust and pad residue to maintain pad-to-rotor contact and prevent brake fade during extended hard driving.
- Floating Mount System: Hardened stainless steel bushings allow independent thermal expansion between hat and ring minimizing warping and vibration.
- 400mm x 36mm Dimensions: Exact OEM-spec diameter and thickness ensure plug-and-play fit with BMW M Series 6-piston calipers across all paint finishes.
- Hand-Finished in USA: Each rotor pair balanced and inspected for runout under 0.002 inches delivering smooth operation from day one.
