The Wilwood DynaPro (DP) Lug Mount forged billet caliper (120-9703-SI) represents a high-performance evolution for braking systems, designed as a precision upgrade or replacement for applications previously utilizing the long-standing Dynalite model series. Engineered for both competition and show use, the DynaPro combines race-proven technology with increased body stiffness and a sleek, fully detail-machined finish.

Constructed from forged aluminum, this caliper offers superior strength and reduced deflection under heavy braking loads. The precision-machined bore and 1.38-inch pistons provide consistent clamping force, while the 5.25-inch mounting centers allow for straightforward integration into existing lug-mount configurations. This model is specifically engineered for use with 0.81-inch thick rotors.
