Scope
Optimizing the current Formula SAE Brake Rotor
Design
Materials – Alloys with better property
Weight – Reduce on thickness
Heat Transfer – Temperature increases during race
Machining – Best if the machine shop can do it
Compatible with ISR 4-Series Calipers and Tilton 77
Series Master Cylinder
