The Forged Billet Dynalite/ST has been specifically designed for high temperature road racing series compact cars. Teamed with Wilwood’s exclusive Thermlock insulated pistons, it gives a small size, high temperature solution for rotors in the 12.19” to 11.00” ranges. The Forged Dynalite are the strongest calipers in the class, with weights starting at 2.90 pounds. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body. This process eliminates the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. With the overall greater strength and reliability of the forging, the reduced deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power.
