W4A Radial Mount-ST
The W4A/ST forged four piston caliper delivers heavy duty stopping power for the road or track. The caliper incorporates race technology into a body design with widespread adaptability. Radial mounting, two options for piston volume, and a rotor diameter ranging from 12.19" to 14.25" give this caliper the versatility necessary to suit all types of heavy weight braking requirements.  

The W4A/ST body is the product of FEA computer design and stress flow forging technology. FEA technology allows the designer to test the prototype in a computer environment to determine the optimal structural design within the dimensional parameters of the component. Stress flow forging produces a part with the internal grain structure of the metal aligned in the direction of the flow of the body contour. The results are a caliper with superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load.    Continue >>
