Drilled Brake Discs are a quick and simple way to improve initial pad bite. With the additional leading edges at each Drilled , the pad is able to grab the rotor just a little bit harder when it's time to stop NOW! Tests have shown (and drivers can feel) the immediate improvement. The holes also provide better cooling under hard use. Pad wear may be accelerated slightly (depending on driving technique), so only high quality brake pads should be considered.The drilled disc surface on the kinetix brake discs dissipate heat more effectively by breaking down surface gases more efficiently. The holes are laser drilled through the discs which reduce brake mass. The drilled brake discs also benefit from keeping braking temperatures rapidly low which helps keep the pad surface from reaching high temperatures that can be caused from hot surface gasses.
The drilled brake discs are way more better than Noisy "Drilled & Grooved" brake discs others sell.
