Upgrade braking performance with the Wilwood Dynalite 4-Piston Brake Caliper, Part Number 120-11578. Designed for applications using a 12.720-inch outside-diameter rotor with a 0.810-inch thickness, this caliper combines a lightweight aluminum construction with a durable gray anodized finish. Its four-piston design provides balanced clamping force and responsive pedal control for performance street, track, and racing applications.
The Wilwood Dynalite caliper uses a 3.500-inch lug-mount configuration for compatibility with properly matched brake system components. The aluminum body helps reduce unsprung weight while maintaining the strength and rigidity needed for consistent braking under demanding conditions. Its compact design is well suited for custom brake upgrades where clearance, performance, and weight reduction are important considerations.
This Wilwood 120-11578 brake caliper is supplied as an individual caliper and should be matched with the correct rotor, mounting hardware, pads, and brake system components for the intended application. Confirm vehicle fitment, rotor specifications, mounting requirements, piston configuration, and left- or right-side placement before installation. Professional installation and proper brake system bleeding are recommended to help ensure reliable operation and safe performance.
