Optional Brake Disc Patterns

TR6 6-Piston Competition Series Caliper

Manufactured by a forging process, the caliper body delivers exceptional stability during continuous braking. The design incorporates extensive weight-reduction pocketing (skeletonization) to minimize caliper mass. This lightweight exterior design aligns with aerodynamic principles while providing superior ventilation and heat dissipation.

Upgraded with high-temperature-resistant stainless steel heat-dissipating pistons, it effectively reduces heat transfer to the brake fluid under repeated braking—ensuring consistent, stable braking performance even under continuous high-load conditions.

72-Vane Ventilation Design

Featuring an advanced 72-vane ventilation design, the rotor maximizes airflow to accelerate heat dissipation while the vehicle is in motion. Especially under aggressive driving conditions, this optimized internal architecture plays a critical role in controlling thermal fade. By eliminating the risk of brake failure during continuous, high-intensity braking, it unlocks ultimate cooling efficiency and rock-solid reliability.

Featuring an ultra-high carbon content of 3.83% infused with premium elements like silicon and manganese, this alloy formulation significantly enhances the rotor's thermal fatigue resistance. It maximizes wear resistance while effectively dampening braking noise.


INSPEED Dedicated Brake Pads

Designed with a low-metallic formula infused with friction materials like silicon carbide and aluminum oxide, delivering enhanced pedal feel.
Validated through extensive LINK dyno testing simulating various extreme environments, these pads deliver excellent initial bite and outstanding high-temperature performance, ensuring stable performance during continuous braking.
Excellent controllability provides superior braking precision while significantly reducing brake dust without sacrificing stopping power.
INS-10 Series: Friction Coefficient 0.38-0.43, Operating Temperature 0-500°C.
INS-20 Series: Friction Coefficient 0.38-0.47, Operating Temperature 0-800°C.
INS-30 Series: Friction Coefficient 0.45-0.53, Operating Temperature 50-900°C.
