I've always found that for street driving the best combo is oem/oem. Sure they can be dusty, but they work great and don't squeak. Theres a reason BMW engineers spent many hours testing and deciding what should go on your BMW.
2nd bimmer for me and i agree, BMW did a lot of research and I'm sure they have chosen the best street pad/rotor combo and if you are driving the car 95% street and 5% track like most who visit the track, sticking to OEM/OEM would be best if you were to choose 1 rotor/pad combo. But ideally, you should buy a 2nd set of rotors/pads with a higher temp range. You'll notice a really big diff on the track!!! I'm sure there are many really good track pads, but I recommend Endless if price isn't an issue and if they make it for Z4s.
