I have the premium drilled R1 concept rotors and love them. I have the akebono top pads that Andy recommended (forgot the name now) and they are good. The only thing I'm not too thrilled about is when it's very cold, they squeak right in the morning more than the OEM did but after I back out of the driveway the squeaks stop. Again this is what happens though with high performance brakes.
I am very happen with my decision over OEM. I wouldn't go back. I love the looks and the performance it provides especially when it's wet, snow, etc. And I don't know why you have a rust problem because I don't recall noticing that a single time, but I know they treat the premium r1 concept drilled. The drilled are nice by the way, not drilled and that is it, but angled at the edge so it's almost like a slot but it's drilled. Again, I love them. When I need new brakes, I'm getting the same ones, including rotors in case I ever need them again but probably won't for years.
