Induction hardened stainless steel rotor with a hard anodized aluminum hub
EPTA disc floatation mechanism, with grooves with ventilation holes for better cooling of interface zone
Optimized lightening holes to avoid vibration onset
Straight 3 mm thick crests protrude from wave shape to outer diameter of the disc forming a radiating area untouched by the pads but with higher thermal inertia than the rest of the disc
