Engineered for the serious G8X enthusiast, the VTT Ultimate Lightweight Rear Brake Kit focuses on maximizing mechanical grip by slashing rotating mass. By replacing the heavy factory single-piston sliding calipers and rotors with VTT’s 6-piston lightweight system, drivers can feel the immediate benefit of reduced rotational inertia during launches and cornering. This configuration is tailored for the user who demands a "race-spec" look with its Red 6-piston architecture but requires a pad compound that functions safely from a cold start. The VTT Street Pads included in this kit offer the perfect balance of performance and civility, ensuring that your G8X remains a dual-purpose weapon capable of dropping ETs at the strip or shaving seconds at the track.
Key Features
Reduced Rotational Inertia: Eliminates over 11 lbs of rotating weight, directly contributing to faster throttle response and improved ETs.
High-Strength Construction: Uses aircraft-grade CNC 7075 aluminum for both rotor hats and caliper brackets to ensure maximum rigidity under load.
Enhanced Cooling: The vented rotor design ensures heat is dissipated quickly, making it suitable for street, track, or drag racing duties.
Stainless Steel Lines: Includes DOT-approved braided stainless brake lines to eliminate the "mushy" feel of factory rubber hoses.
Optimized Pad Surface: The 6-piston design utilizes a larger pad surface area compared to 4-piston alternatives for increased thermal capacity.
