034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit

The 034Motorsport 345mm x 24mm 2-Piece Floating Rear Brake Rotor Upgrade Kit is engineered for precision and performance, specifically designed for the G20 BMW M340i and A90/A91 Toyota Supra. This complete replacement kit integrates seamlessly with the factory rear calipers, enhancing your vehicle's braking capabilities.

Key Specifications

• Weight: Approximately 16.9 lbs, significantly lighter than the OEM rotor (18.6 lbs)
• Material: Central hat made from 6061-T6 aircraft-grade aluminum; rotor rings constructed from a proprietary metal alloy
• Dimensions: 345mm diameter, 24mm thickness

Design Features

This rotor upgrade features a true 2-piece design, allowing for a floating mount system that utilizes high-strength alloy steel bobbins. This construction accommodates thermal expansion and contraction, ensuring optimal performance under extreme conditions. The rotor rings can be replaced independently, lowering long-term maintenance costs.

The rotor face employs a J-Slot design, which increases the braking surface area compared to traditional drilled rotors. This design also minimizes noise and enhances pad cleaning, while mitigating the risk of cracking associated with drilled rotors. Additionally, the 36 directionally curved vanes promote efficient airflow, improving heat dissipation during intense braking scenarios.

Performance Testing

Thoroughly tested in high-intensity motorsport environments, the 034Motorsport rotors have proven their ability to significantly enhance braking performance and thermal management. These rotors are ideal for both extreme street use and track applications, allowing for consistent and reliable stopping power.

Fitment
