A few more things to add Brembo is cast ST is forged Brembo is one piece where ST is two. They aret the same size, dimension or weight as a matter of fact there are so many differences between ST and Brembo anyone who has ever seen the two can instantly tell the difference, not just in the calipers but the hats are bigger on ST and the rear rotors arent 380(like Brembos) and thats just a few of the obvious differences you can see with your eye from a mile away. Both are good brakes however, neither company is copying each other, they are polar opposites as far as BBK concepts are concerned. I have driven an e92 m3 with all three configurations(stock, Brembo, ST) and I think the Brembos and ST are very comparable.
