W6A Radial Mount-Quick-Silver/ST
Quick-Silver / ST series W6AR/ST nickel plated forged billet calipers, with six Thermlock pistons, deliver championship proven performance with heavy duty stopping power and reliability for sustained high heat competition. W6AR/ST calipers incorporate race technology into a radial mount body design with widespread adaptability and an expanded rotor compatibility range from 12.19” to 15.00”, including track update options for all W6AR Big Brake kits. Thermlock pistons, high-temp seals, SRS bridge plates, and two-piece bleed screw assemblies are standard in all calipers. Four high-temp race only brake pad compounds in the 6617 pad type allow precise tuning of the brake response, friction requirements and temperature range for all types of high performance and competition applications.   

The W6A/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 >>
