I'm thinking of gettting a set of M90 rotors drilled down through the center at their thickest section from one end to the other. The hole would be about an inch in diameter or the biggest diameter hole that would leave 3/16-1/4" wall thickness. I think that it would reduce the weight of the rotors by about 1/3 and therefore take less HP from the engine to turn them. I spoke with a shop who said that it is feasible and they gave me a price to do a set of rotors.
I also have an idea about how to check the balance of the rotors after they are drilled to make sure that the drilling hasn't taken them out of balance.
Does anyone think this is a good idea or is it crazy talk?
