Tesla Composite Grey Hat Brake Discs

Tesla Composite Grey Hat Brake Discs are factory-upgraded brake components designed by Tesla specifically for its high-performance electric vehicles. Featuring an innovative dual-layer composite structure, these discs achieve industry-leading levels of lightweight construction, heat dissipation efficiency, and durability through breakthroughs in materials science and engineering design.

The friction ring undergoes laser hardening and stress relief treatment, with a flatness tolerance of ≤0.03mm, ensuring vibration-free high-speed braking.

The sharp-edged groove design effectively scrapes away the “glazed layer” from brake pad surfaces, maintaining a consistently stable coefficient of friction (μ=0.48 vs OEM iron discs at 0.32).

Redefining the performance benchmark for electric vehicle braking systems through a dual-layer composite structure, Tesla valve ventilation technology, and ceramic coating process. Its lightweight design directly enhances handling and range, while high-temperature resistance meets track-level demands. Maintenance-free operation reduces daily usage costs. For Tesla owners seeking OEM quality and ultimate performance, this represents the ideal choice balancing track competition and everyday driving.

•Carbon fiber reinforced silicon carbide matrix. Offers superior heat resistance, lighter weight, and longer life vs. traditional iron discs.

•Ceramic layer on the disc surface. Reduces brake dust, corrosion, and wear while improving daily driving pedal feel.

•3D matrix design with continuous carbon fiber. Enhances strength and heat management for extreme performance.

•Resists brake fade, provides stable friction at high temperatures, and can shorten braking distances.

•Includes forged calipers and track fluid. Ensures all components work together optimally for maximum performance and safety.
