I have heard so many arguments about what is a better rotor and 50 million reasons why one is better then the other. The only true way to find out, is to try em all. And realistically no one goes thru 10 sets of rotors in a cars lifetime.
(cept for that 350 000 mile Aurora...anyway....) back on track
I have cross drilled and slotted rotors from Rototech and its stops my 4000 lb boat just fine, the slots dont go all the way to the edge, the only way I will be able to compare is to throw some RSM rotors with slots all the way to the edge next time.
Any way you look at it, brakes make your car stop, so get what you feel is best, dont over read the reviews cuz then you will go loopy.
Aftermarket brakes will always be better then stock. If the drill holes in my rotors end up with micro cracks, then I wont ever get em again, and I will go for something different, but I wont know til I try.
Point being, get what you think works best for you and get what you can afford.
