Wilwood 120-16438 Forged Dynalite Internal ST Universal Lug Mount Caliper 4 Pistons
Forged Dynalite Internal-ST
The Wilwood Forged Billet Dynalite Internal/ST has been specifically designed for high temperature road racing series compact cars. Teamed with 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, Designed with a single split bridge and spacer less design to enhance strength and appearance.
The Forged Billet Dynalite Internal is the strongest caliper in the class, with weights starting at 3.00 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. Incorporating a radius in this transition area substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement tests have proven the Forged Dynalite to outperform all existing styles of this popular caliper size.
