When you replace rotors you want to go lighter aluminum hats, slotted to cross drilled. Less weight less rotational mass = faster car!

Cross drilled are great in the rain, but removing surface areaa with the slots and holes the pad touches reduces braking. The rotors will stay cooler with a cross drilled for long periods of high speed braking.
