W6A Radial Mount
The W6A forged six 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 redisigned rotor diameter range from 12.19" to 15.00" give this caliper the versatility necessary to suit all types of heavy weight braking requirements.  

The W6A 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 >>
