Wilwood 140-10542 Dynapro Radial Front Drag Brake Kit 11.75" Vented

The Wilwood 140-10542 is a Dynapro Radial (NDPR) Front Drag Brake Kit featuring an 11.75-inch vented rotor, purpose-built for drag racing applications where OEM brakes are too large to fit inside narrower 15-inch drag wheels. This kit delivers the stopping power and thermal performance needed for serious strip use in a compact, bolt-on package.

The heart of this kit is the forged billet Narrow DynaPro Radial (NDPR) four-piston caliper, featuring heavy-wall stainless steel pistons that resist corrosion and slow heat transfer from the brake pads. The calipers mount via specially designed radial caliper brackets that bolt directly to the factory OE caliper mount — no spindle modifications or steering-linkage changes required. The kit is fully compatible with the stock master cylinder output.

Key Features:

• Forged billet NDPR 4-piston radial mount calipers
• Heavy-wall stainless steel pistons for corrosion resistance and heat management
• 11.75" (298.5mm) vented rotor — 0.81" (20.6mm) thick for increased durability
• Compact caliper design engineered to clear popular 15" drag racing wheels
• Radial mount brackets bolt directly to OE caliper mount — no spindle mods needed
• Includes street/strip brake pads with strong fade and heat resistance
• Minimum recommended wheel diameter: 15 inches
• Rotor construction: Vented, solid surface

Application Notes: Kits with 0.81" rotors are recommended for vehicles over 2,800 lbs or for lighter vehicles running extreme speeds where added rotor durability is desired. The kit installs without spindle or steering-linkage modifications and is fully compatible with the factory master cylinder.
