Wilwood 120-16438 Forged Dynalite Internal Brake Caliper

The Wilwood Forged Billet Dynalite Internal/ST caliper is engineered for high-temperature road racing applications on compact cars. This lightweight, high-performance disc brake caliper is optimized for rotors ranging from 11.00" to 12.19" diameter and features Thermlock® insulated pistons to minimize heat transfer and protect brake fluid integrity during demanding competition use.

Key Features:

• Stress-flow forged construction re-aligns metal grain structure for maximum strength
• FEA-generated radial transition design eliminates stress risers between piston housing and bridges
• Single split bridge with spacer-less design enhances structural rigidity and appearance
• Thermlock® insulated pistons reduce heat transfer to brake fluid
• Weighs approximately 3.00 pounds for minimal unsprung weight
• Superior resistance to deflection and caliper separation under high loads

The forging process used in the Dynalite Internal eliminates the internal grain structure interruptions inherent in machined billet calipers, resulting in superior strength and stiffness. Structural deflection and volume displacement testing confirms the Forged Dynalite outperforms all other calipers in this popular size class, making it the ideal choice for serious road racing and high-performance street applications.
