You might also note that Aston Martin, Lamborghini, Maserati, Bugatti, Ford, Jaguar, Lotus, Mclaren, Mercedes, MG, Noble, Pagani...etc...ad nauseum...also use cross drilled brakes on their high-performance machines...so they must have a fairly significant benefit from a performance standpoint.

Yeah, i cant understand it, and om just after a good theoretical engineering explaination, cus it doesnt all add up in my head!!!!
