W4A Radial Mount -Quick-Silver
Quick-Silver series W4AR nickel plated forged billet four piston calipers provide matched bias rear braking for use in conjunction with the W6AR front calipers. W4AR 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 update options for all W4AR Big Brake kits. Stainless steel pistons, high-temp seals, SRS bridge plates, and two-piece bleed screw assemblies are standard in all calipers. Two high performance street, and 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 W4A 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 >>
