Rotor Adapter Dynamic Mt 4.00 OD Clamp 6x5.50

The Rotor Adapter Dynamic Mt 4.00 OD Clamp 6x5.50 is a precision-engineered brake system component engineered for high-performance vehicle applications requiring robust rear inboard rotor mounting. Wilwood's adapter serves operators and technicians who demand reliable braking performance under demanding conditions—whether in tactical vehicle builds, law enforcement fleet maintenance, or military-specification platforms. This aluminum rotor adapter bridges the gap between your brake caliper assembly and rotor, ensuring proper alignment and load distribution across the 6 x 5.50-inch bolt pattern.

Constructed from aluminum and finished with gray anodized coating, the adapter provides corrosion resistance while maintaining a lightweight profile—critical in vehicles where unsprung weight directly impacts handling and braking response. The 4.00-inch outer diameter clamp interface ensures a secure, concentric fit that prevents rotor runout and brake fade during extended operations. Wilwood's engineering eliminates flex and guarantees consistent brake modulation, a non-negotiable requirement for tactical or enforcement vehicles operating in high-stress scenarios. The gray anodized finish protects against salt spray and road contaminants while maintaining a professional appearance.

This adapter is ideal for operators upgrading to performance or regulation-compliant brake systems on rear-wheel-drive platforms with six-bolt rotor patterns. Installation integrates seamlessly into existing rear inboard setups on vehicles requiring precision stopping power and thermal stability. Technicians and fleet maintenance personnel benefit from Wilwood's repeatable tolerances and standardized bolt pattern compatibility, reducing diagnostic time and ensuring consistent results across multiple platform applications. Weighing just 0.42 pounds, it adds negligible rotating mass while delivering the structural integrity necessary for sustained high-performance braking cycles.
