Product details
With 4 pistons and 1.38/1.38-inch bore dimensions, the red Wilwood Dynalite-M brake caliper must be matched to the brake system rather than selected by finish alone. Its 0.81-inch rotor-width specification is separate from rotor diameter. The four-piston Dynalite-M has a forged body shaped to improve outboard clearance and is used in Wilwood Classic Style assemblies. Match the exact mounting geometry and rotor sweep rather than treating every Dynalite model as interchangeable. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.

Fitment & Compatibility
This caliper requires the measured 0.81-inch rotor-width configuration and the matching lug bracket on 5.25-inch centers. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Confirm the 1/8-27 NPT hydraulic inlet, pad outline and total piston area with the rest of the brake system before assembly.
