产品组合

Composite hub brake discs are core to BMW’s driving performance—especially for M models (e.g., M3, M4) and sport variants. They bear intense loads during high-speed braking or track driving, while their two-piece design (cast iron friction ring + aluminum hub) cuts unsprung weight by up to 30% , boosting handling precision. Meeting ECE R90 and IATF 16949 standards , our discs match BMW’s OE specs, integrating seamlessly with its DSC system and regenerative braking (for hybrids) to deliver consistent, responsive stopping power.

Brake Discs Features

OE-matched for BMW performance lineups: Fits M3/M4 and sport models, ECE R90/IATF 16949 certified, direct bolt-on installation without mods .
Dual-material composite structure: High-carbon cast iron friction ring + forged aluminum hub, connected via steel pins for lightweight and durability .
Heat-resistant floating design: Ventilated grooves enhance cooling; floating layout allows radial expansion to avoid thermal deformation .
Corrosion-resistant coating: Zinc-nickel/Geomet finish passes salt spray tests, resisting rust from road salt .
NVH-optimized: Non-directional friction surface + damping components reduce vibration and noise .

Brake Discs Benefits

Sharper handling: 30% weight reduction lowers unsprung mass, improving steering response and cornering stability .
Reliable high-performance braking: Heat dissipation and anti-deformation design eliminate fade during track sessions or emergency stops .
Seamless system compatibility: Works with BMW’s DSC and hybrid regenerative braking, preserving factory brake feel .
Long service life: Wear-resistant cast iron and anti-corrosion coating reduce replacement frequency .
Quiet, premium experience: Low noise and dust keep wheels tidy, matching BMW’s luxury positioning .
