Wilwood Narrow Dynapro 4 Piston Caliper Radial Mount - Type III Anodised Grey, 4.80 sq/in, 0.81 Inch (20.57mm)

The Wilwood Narrow Dynapro 4 Piston Radial Mount Caliper provides reliable braking performance in demanding environments. It uses a stress-flow forged aluminium body with precision-engineered features to deliver strength, durability, and consistent pedal feel under high loads.Discover the key features of this caliper:Stress-flow forged aluminium body: This forging process aligns the internal grain structure of the material to follow the caliper s contours, increasing overall strength and fatigue resistance which results in a stiffer body capable of maintaining braking precision under extreme loads.FEA-generated body design: The radial transition between piston bores and caliper bridges removes machining steps and shoulders in high-stress areas, enhancing resistance to deflection and separation so you maintain a firm pedal and stable braking performance.Lightweight construction: With a total weight starting from 1.63kg, the caliper reduces unsprung mass which improves suspension response and handling stability during braking.Heavy wall stainless steel pistons: These pistons resist corrosion and limit heat transfer from the pads, helping to control brake fluid temperature for consistent braking performance over extended use.Stainless SRS bridge plates: These plates protect the caliper bridges from pad gouging while reducing vibration and noise, improving both longevity and braking comfort.Internal fluid passages: By eliminating the need for external crossover tubes, these passages reduce potential leak points and streamline installation while maintaining reliable fluid transfer.Four-corner bleed screws: This arrangement allows you to fully evacuate air from the system in any mounting position, ensuring effective and consistent brake feel after servicing.This caliper enables you to achieve high braking efficiency while maintaining a controlled pedal response in challenging driving conditions. Its combination of strength-focused engineering and user-focused service features makes it a valuable addition to your braking system setup, providing reliable performance and durability for demanding applications.Suits rotor diameters: 273mm (10.75") to 320mm (12.60")Mount centres: 120.7mm (4.75")Calipers are non-handed and sold individually.Please note: Brake pads are not included but are available to purchase from our Motorsport brake pad category.
