Wilwood 140-12548-D DPL Single Rear Dynamic Disc Brake Kit SA Drilled

The Wilwood 140-12548-D Billet Dynapro Lug-Drive (DPL) Single Rear Dynamic Disc Brake Kit is engineered for high-performance vehicles that place heavy demands on rear braking systems. This kit is especially well-suited for cars that rely primarily on rear brakes for deceleration, as well as high-speed, heavy-weight vehicles that generate above-average rear brake heat. The rotors feature a Super Alloy stainless steel construction with an SA drilled surface pattern for enhanced heat dissipation and bite.

Key Features:

• Lug-Drive Rotor Mounting System: Eliminates traditional rotor bolts entirely — a large single internal snap-ring retains the rotor in the hat for fast, tool-free rotor swaps
• Thermally Independent Rotor Design: Rotors move freely relative to the hat during heat cycles, removing all thermally generated stress from the rotor attachment points for flatter, truer running rotors
• Spring-Loaded Stainless Steel Lug-Drive Inserts: Replaceable inserts in each lug-drive slot protect the aluminum hat from wear caused by brake torque loading
• Two Rotor Diameter Options: Available in a traditional 11.44" diameter or a compact 11.25" diameter for clearance compatibility with bead lock rims
• SA Drilled Rotor Surface: Drilled pattern promotes cooling and helps evacuate gases and debris at the rotor face
• Single Caliper Configuration: This kit is configured with a single caliper per corner for a clean, weight-efficient rear brake setup
• Billet Aluminum Hat: Precision-machined hat is protected from distortion caused by rotor thermal expansion and contraction

The DPL lug-drive system represents a significant advancement over conventional bolt-on rotor designs. By allowing the stainless rotor to float independently within the hat, this system dramatically extends the service life of both the rotor and hat while maintaining consistent brake performance under severe thermal conditions. Kits are also available in dual caliper configurations for even greater stopping power.
