Wilwood 140-17884-D Forged XRD Rear Disc Brake Kit with Lug-Drive Rotors

The Wilwood 140-17884-D is a high-performance rear disc brake kit featuring Forged XRD Lug-Drive Dynamic Stainless Super Alloy rotors designed for drag racing and high-speed applications. This kit is especially beneficial for vehicles that rely heavily on rear brakes for stopping power and any high-speed, heavy-weight cars that generate above-average rear brake heat.

Key Features:

• Innovative lug-drive rotor mounting system eliminates rotor bolts for simplified installation
• Large internal snap-ring retains rotor in hat, allowing rotors to expand and contract independently through heat cycles
• Removes all thermally-generated stress from rotor attachment points for flatter, truer-running rotors
• Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect aluminum hat from wear
• Dynamic stainless super alloy rotors provide superior heat resistance and durability
• Prevents hat distortion from thermal expansion and shrinkage stresses
• Available in single and dual caliper configurations
• 2.81-inch offset with 0.68-inch rotor width

This kit is engineered for drag racing and other demanding applications where consistent rear brake performance under extreme heat is critical. The lug-drive system ensures optimal rotor-to-hat interface while eliminating common failure points associated with traditional bolt-on rotor designs.
