Wilwood 140-16678-Y Forged Narrow Dynapro-P Radial Rear Brake Kit – Le Mans Yellow

The Wilwood 140-16678-Y is a Forged Narrow Dynapro-P Radial Rear Brake Kit finished in Le Mans Yellow powder coat, engineered for high-performance street and track use. This complete caliper, pad, and bracket kit is a direct bolt-on upgrade that installs to factory rear caliper mounts without requiring additional adapters or modifications.

At the heart of this kit are Wilwood's Forged Narrow Dynapro-P Radial (NDPR-P) 4-piston calipers. The forged aluminum construction resists flex and heat while minimizing unsprung weight, and stainless steel pistons further reduce heat transfer and corrosion for long-term reliability. The radial mount design with 3.50" (88.9mm) caliper mounting bolt spacing ensures a precise, rigid fit.
