Front Brake Rotor for Porsche

• Floating brake rotors feature a 2-piece design consisting of a cast iron friction ring and an aluminum alloy bell hat, connected by floating pins/brackets with a small radial and axial clearance. This structure allows the friction ring to expand and contract freely under heavy braking heat, effectively eliminating thermal distortion, warping, and brake judder.
• Selective coating refers to a surface treatment process where high-temperature resistant anti-corrosion coating is only applied to specific non-friction areas of the brake rotor, including the hat, mounting surface, outer edge and vane channels, while the friction ring remains uncoated to guarantee stable braking efficiency and heat dissipation.
• This localized coating technology effectively prevents rust and discoloration without compromising braking performance

1. Excellent corrosion resistance

Effectively prevents rust and discoloration on hat, vane and non‑friction surfaces.
2. Uncompromised braking performance

The friction ring remains uncoated, ensuring stable friction coefficient, no brake fade or noise from coating degradation.
3. Superior heat dissipation

No coating on braking surface avoids heat insulation and maintains optimal thermal efficiency.
4. Longer service life

Protects vulnerable areas from oxidation and extends overall rotor durability.
5. Premium appearance

Clean, uniform finish enhances vehicle aesthetics, especially under alloy wheels.

6. Cost-effective solution

Delivers anti‑corrosion performance close to fully coated rotors at a more competitive cost.
7. Stable quality & OE compatibility

Meets original equipment standards for balance, runout and fitment.
