I was talking to someone about the cast iron calipers. I showed him both: the aluminum brembo, and the cast iron ATE 500E front calipers. He said that the structure of cast iron has a natural dampening effect. Plus they are heavier which makes them move slower (more inertia) and the cast iron ones are stronger. But I do not know about the braking distances.

Brembo aluminum vs ATE cast iron. It would be a good test to see which one stops faster and which one resists fade the best.

Im more interested in stoping distances, than noise....unless its unbearable....maybe someone can give me a ride with the brembo caliper set up???
