Wilwood 140-14640-R Dynapro Radial-MC4 Rear Disc Brake Kit with GT Slotted Rotors Red Calipers

The Wilwood 140-14640-R is a Dynapro 4 Radial-MC4 rear axle brake kit engineered to replace factory disc brakes on late-model high-performance vehicles. Featuring the integrated MC4 parking brake assembly, this kit is designed to complement front big brake upgrades while delivering a significant leap in rear braking capacity, durability, and visual appeal.

At the heart of the system are Wilwood's Dynapro Radial 4-piston calipers finished in an eye-catching red powdercoat, paired with BP-10 high-friction compound brake pads and oversized 12.19" GT slotted rotors. The slotted rotor surface promotes consistent pad bite, improved outgassing, and better heat dissipation compared to a standard smooth rotor, reducing fade under demanding driving conditions.

Key Features:

• Dynapro Radial 4-piston calipers in red powdercoat finish for high clamping force and aggressive style
• 12.19" GT slotted vented rotors for superior cooling and fade resistance
• BP-10 compound brake pads matched for street performance use
• Integrated MC4 mechanical parking brake assembly included
• Engineered to maintain compatibility with OE master cylinder output and ABS function
• Calibrated to meet individual vehicle front/rear brake bias requirements
• Bolt-on installation using common hand tools
• Complements big wheel, tire, and suspension upgrades on custom and modified vehicles

This kit is part of Wilwood's Street Performance lineup, purpose-built for enthusiasts who demand more than factory braking without sacrificing street drivability. All components are engineered and manufactured in the USA by Wilwood Engineering, a leader in high-performance disc brake systems since 1977.
