Wilwood 140-15318 Classic Series FDLI Front Disc Brake Kit 11.50" 1-PC Rotor & Hub

The Wilwood 140-15318 is a Classic Series front disc brake conversion kit engineered specifically for Classic Performance Products (CPP) GM Tri-5 drop spindles. Featuring the proven FDL-M four-piston forged aluminum caliper paired with an 11.50" diameter x 1.00" thick one-piece cast iron rotor with integrated hub, this kit delivers a clean, effective upgrade for builders seeking serious stopping power without sacrificing wheel clearance or fitment.

The FDL-M (Forged Dynalite) caliper is a refined evolution of Wilwood's legendary Dynalite design, engineered to provide maximum wheel clearance among four-piston calipers in its size class. The caliper's compact forged aluminum body keeps unsprung weight low while delivering strong, consistent clamping force.
