Re: slotted rotors vs standard
Advantages of DBA Longlife Slotted Rotors:
Unidirectional slotting (left and right), to increase pad bite, reduce fade and deliver exceptional braking performance.
Slots continually de-glaze the brake pads, improving efficiency and reducing rotor scoring. They even out-wear across the brake pad faces, increasing the effective contact area and extending rotor life.
Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt.
Slotting also combats "out-gassing", where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power.
Provide a cost effective solution to improve the stopping performance of vehicles which are "under-braked" (such as many large four-wheel drives).
