My dealer mentioned that my rotors have some high spots causing brake pulsation. The original rotors are very expensive and almost look like they are 2 piece since the center hub is a different metal composition than the rotors. Are they 2 piece or just a combination of 2 different metals. Is this to save weight. My question is since I don't put a lot of miles on my car (5k/year). I see some complete kits with rotors and pads for a lot less than oem. They aren't 2 piece or dissimilar metals so I assume it will add a little unsprung weight. I like them because they are drilled and slotted. Can I use these kits without any detrimental effect on my car. Any suggestions greatly appreciated. Thanks
