I've got the 4 piston 355mm on the front and 4 piston 328mm on the rear of my E430. I like them but I'm not sure they are "worth" it. They cost quite a lot even buying them used. I like modding so I'm OK with that but there are probably better things you could spend money on then Brembos. Peter_02AMG had the 6 piston setup on his E55.
