ASHIMA ARO-09 Ai2 Brake Disc 6-hole - rot

ASHIMA ARO-09 Ai2 Brake Disc 6-hole - rot

Ai2 - one of the lightest 1pcs. stainless steel rotor.

Some said AiRoTor would never work . Then 3 years and several World Championships later others said it would be impossible to go lighter whilst offering the performance level that made AiRoTor the bestselling aftermarket rotor of all time . Well they were wrong and Ai2 proves it!

Ai2 offers a staging 23% weight saving over the AiRoTor without impacting braking performance.

Specifications of the Ashima Ai2:
  • Super Light weight (160mm/ 66g, 180mm/ 93g)
  • High grade SUS410 stainless steel
  • Grounded and Hardened to 47 HRC


Due to extreme low mass Ai2 Rotors heat-up more than heavier rotors which may adversely impact some lower spec systems during prolonged braking events. However, conversely due to the extreme low mass they also cool very fast, so with proper/normal braking consideration the heating/cooling effect can be balanced.
