Wilwood 140-16559-D Dynalite Single Floater Front Drag Disc Brake Kit

The Wilwood 140-16559-D is a Dynalite Single Floater (DLSF) front drag brake kit purpose-built for lightweight drag racing vehicles using spindle mount brakes. Designed for direct bolt-on installation to Afco Racing strut/spindles and Santhuff strut/spindles with spindle mount wheels, this kit delivers reliable staging brake performance and supplementary stopping power for competition applications.

The DLSF single-piston aluminum caliper and lightweight steel cross-drilled rotor work together to deliver strong static holding power — ideal for use as a staging brake or as a supplementary front brake on vehicles relying primarily on parachutes and rear brakes for deceleration. Aluminum hats are included to mount the rotors directly to spindle mount wheels, keeping unsprung weight to an absolute minimum.
