RH-001 Rotor Hat Adapter (Shown installed above)

Advantages of using a Porsche Turbo rotor with Electro-Dynamics rotor hat adapter:
1. More mass to absorb heat
2. More vanes and internal surface area to dissipate heat
3. Drilled holes of the rotor are reportedly cored when cast to provide a more stable grain stucture.
4. A wider swept area is available when utilized with the Porsche Turbo caliper.
