Dynapro-ST Radial Mount

The Wilwood Dynapro-ST four piston radial mount calipers (DPR-ST) combines the versatility of radial mounting with a with the ultimate heat protection using Thermlock® pistons and extreme durability in adverse conditions. The Dynapro series of calipers has become a favored choice for a broad range of sports, rally, and off-road driving applications. Thermlock® pistons in the ST models block heat transfer from the pads and reduce temperatures in the caliper, fluid, and seals by up to 25% over standard stainless steel pistons.

The strength of the Dynapro is a combination of process and design. The process of stess-flow forging re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a part with superior strength over machined block billet parts or castings. The FEA generated body design features a radial transition between the piston bores and caliper bridges. This eliminates macined steps and shoulders in this critical strength area and substantially increases the resistance against deflection and body separation under high load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. The bottom line is a firm pedal with outstanding stopping power.
