Wilwood 140-14089-DR Dynapro Radial-MC4 Rear Disc Brake Kit with Drilled Rotors

The Wilwood 140-14089-DR Dynapro 4 Radial-MC4 Rear Disc Brake Kit is a complete bolt-on rear brake upgrade engineered to replace factory disc brakes on late-model, high-performance vehicles. Designed to integrate seamlessly with front big brake upgrades, this kit pairs Wilwood's proven Dynapro Radial 4-piston caliper with an integrated MC4 mechanical parking brake assembly for a clean, purpose-built rear brake solution.

At the heart of the kit are oversized 11.00" cross-drilled rotors that improve heat dissipation and bite, paired with BP-10 high-performance brake pads for consistent, fade-resistant stopping power. The system is engineered to remain compatible with the OE master cylinder output, factory ABS function, and individual vehicle brake bias requirements — no hydraulic system modifications required.

Key Features:

• Dynapro Radial 4-piston calipers finished in red powdercoat for high-performance aesthetics
• 11.00" cross-drilled rotors for improved thermal management and wet-weather bite
• Integrated MC4 mechanical parking brake assembly — no separate e-brake caliper required
• BP-10 compound brake pads for high-capacity street performance braking
• Engineered to match OE master cylinder output and ABS function without hydraulic system modifications
• Designed to complement front big brake kit upgrades on customized and performance vehicles
• Ideal for vehicles with upgraded wheels, tires, and suspension requiring increased brake capacity

The 140-14089-DR is the drilled rotor variant of the 140-14089 series, offering the combination of high-capacity braking performance and aggressive styling that complements custom builds and street performance applications alike.
