Wilwood 120-16686 Narrow DynaPro-P Radial Mount Disc Brake Caliper - 4-Piston

The Wilwood Narrow DynaPro-P (NDPR-P) is a four-piston radial mount disc brake caliper engineered for high-performance applications where space is at a premium. Combining the flexibility of radial mounting with a sleek, low-profile body, this caliper delivers superior clamping force with outstanding durability even in the most demanding conditions.

Designed specifically for rotors with limited swept area, the Narrow DynaPro-P features a slim profile that allows fitment in tight wheel packages without sacrificing braking performance. The caliper is built around four 1.12" pistons and a 4.75" radial mount spacing, paired with a bridge bolt design for use with 0.81" thick disc rotors.

Key Features:

• Four-piston radial mount design for precise, even pad clamping force
• Narrow low-profile body engineered for rotors with limited swept area
• 1.12" pistons with 4.75" radial mount and bridge bolt configuration
• Compatible with 0.81" thick disc rotors
• Uses Wilwood 4812 brake pad shape for broad pad availability
• Stress-flow forged construction for superior strength over machined billet or cast alternatives
• FEA-optimized body design with radial transitions between piston bores and bridges to resist deflection and body separation
• Lightweight at just 3.9 lbs for reduced unsprung weight
• Extreme durability suited for sports, rally, off-road, and track applications

The Narrow DynaPro-P is a purpose-built solution for builders and racers who need a high-performance radial mount caliper in a compact package. Its forged construction and FEA-engineered body ensure consistent braking performance under sustained high loads.
