Slotted, drilled, slotted and drilled: which one to choose?
You should choose slotted only rotors for best performance, endurance, and highest temperatures. The drilling reduces the weight of the rotor, and therefore the maximum temperature and endurance the rotor can take is also reduced. If you are after rotors that heat up to operating temperature quicker, you might want drilled rotors in some applications. However, for performance driving, racing, or track, we advise slotted only.
