Are cross drilled slotted rotors better?

Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.

Is there a benefit to drilled and slotted rotors?

The design of drilled and slotted rotors offer drivers the advantages of both designs with minimal side effects. The drilled holes give you better cooling for the heat generated by heavy braking, while the slots work to sweep away gas and dust which come through braking.

What is the difference between cross drilled and slotted rotors?

Drilled rotor: a solid rotor with a series of holes drilled into the rotor surface (a.k.a. cross-drilled rotor) Slotted rotor: a solid rotor with grooves or lines machined along its surface. Vented rotor: a brake rotor with two discs (inner and outer) connected by ribs.

Do slotted brake rotors make a difference?

When compared to standard rotors, the drilled and slotted rotors tend to offer enhanced gripping experience, and it is more responsive and has an efficient performance when it comes to the braking system. The holes help in boosting friction efficiency between the pad and disc significantly.

Can you turn cross-drilled rotors?

Can You Resurface Drilled & Slotted Rotors? It is possible to machine or cut a drilled & slotted rotor. To do so, the brake lathe should be set to its slowest setting. Whenever brake pads are replaced, the rotors should also be replaced or resurfaced to allow the new pads to be properly bedded.

What is the advantage of slotted rotors?

Slotted rotor grooves offer two distinct benefits under heavy braking: brake fade, from high-temperature brake pad outgassing, can be significantly reduced, allowing gases to escape through the slots; and the grooves shave off thin layers of brake pad material, reducing glazing and improving braking consistency.

What brake pads are best for drilled and slotted rotors?

Ceramic pads work fine on cross drill slotted rotors. Metallic pads will work just as well, up to a point. Ceramic pads tend to last longer than metallic pads and score the rotors less. Under extreme braking conditions, a ceramic pad will dissipate heat and cool down faster than a metallic pad.

Are slotted rotors good for trucks?

In a word, yes. Drilled and slotted rotors are for real – they can improve braking performance in a lot of different situations. In many situations where a stock set of truck brakes would overheat and fade, after-market rotors will continue to perform.

Can you turn cross drilled rotors?

Can you resurface cross drilled and slotted rotors?

How do you break into drilled and slotted rotors?

How to break in new brake rotors and pads

  1. Engage hard braking at 40 mph. Do not come to a complete stop.
  2. Go 50 mph and jam the brakes just to the point of engaging ABS all the way down to 10 mph.
  3. Then go 65 mph and slow the car down to 15 mph to finish it up.
  4. Park the car and let the brakes cool down for 20 minutes.
