Crossed drilled rotors and slotted rotors (and rotors that are both slotted and drilled) are designed to allow gases to escape that build up between the brake pad and brake rotor. Another important advantage to using drilled and slotted discs is the constant renewal of the pad friction material.

The advantage of slots is that it dramatically improves stopping power.
What is the advantage of drilled and slotted rotors. The advantage of the premium dimpled drilled and slotted brake rotors is the superior braking power you will experience over your stock brake system. As such, slotted brake rotors have more braking power as compared to drilled brake rotors. Drilled and slotted rotors offer drivers the consistent performance they want without changing the responsiveness of the brake pedal.
The problem with regard to our question of drilled and slotted rotors is that those practices act to reduce the mass of the rotor, reducing the desired heat transfer. Great initial bite in wet and dry conditions, superior cooling capacity, decreased brake fade, longer life, and fantastic looks. Blank rotors offer the best bang for your buck.
There is also a combination of the slotted and drilled brake rotors. Drilled & slotted brake rotors are also are fine for general use in street vehicles. This process gives you the confidence needed as a driver that you can handle whatever situation might come your way.
The hybrid of drilled and slotted brake rotors offers benefits from both worlds. For this reason, even in the case of wet roads, the system responds efficiently from the very first braking operation. That is an advantage of larger diameter rotors, along with the greater leverage of increased size.
This hybrid comes with the advantages provided by the two types of brake rotors. On the other hand, the slot helps in sweeping away gas as well as dust, which comes from braking. However, for track racing (high speed stops), slotted rotors are the better choice.
One of the biggest benefits to using a slotted rotor is that the slots help pull brake dust away from the pads. Unless you are looking into buying forged drilled and slotted rotors, then there is little advantage in purchasing the rotors, besides how they look. This makes drilled and slotted rotors are the choice of many performance enthusiasts, but they also work great on your daily driver for the exact same.
Crack on a drilled rotor. 2018 porsche 911 gt3 drilled brake rotors | porsche. The general consensus seems to be that drilled and slotted rotors offer better performance than “blank” rotors.
This is simply not the case. Heavier vehicles require more energy to come to a stop safely, and this type of brake rotor excels at delivering it. Drilled and slotted brake rotors offer the best of both worlds:
This is why high end bmw, porsche, corvette, and mercedes rotors are drilled, not slotted. Not cooling or reducing unsprung weight or deglazing the pad. The entire rationale behind slotted and cross drilled brakes is to vent gases produced as a byproduct of the pads compressing the rotors.
They sometimes experience premature wear. Each brake disc is machined with four to five slots per side, depending on the vehicle, that extends off the edge of the rotor surface to remove dust and water. Cross drilled rotors are oem style blank rotors that have been cross drilled to allow.
List of the cons of drilled and slotted rotors. Better braking in muddy conditions. That’s where slotted and drilled rotors come in.
The holes also interrupts the sheet of water that can deposit on the braking surface in the rain. At one point in time race cars did have cross drilled rotors, and this is probably where the idea that they offer increased performance came from. Drilled and slotted rotors do work particularly well for tow vehicles, trucks, and other cars that carry heavy loads.
Some may even say they decrease the braking power of your car. By reducing the debris between your pads and rotors, you allow more of the pad’s surface area to come in contact with the rotor, which means 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.
Furthermore, the holes drilled provide a better cooling effect from the heat being produced by heavy braking; This allows your brakes to run cooler and stop better. Customers always ask, what is the advantage of drilled and or slotted brake rotors over stock plain brake rotors?
They're stronger than drilled rotors, and they provide some other advantages as well, such as additional biting surfaces. Additionally, slotted rotors are stronger and less prone to cracking compared to drilled rotors as the structural integrity of the slotted rotors is not compromised during the machining process. Plus, they let water escape more easily from the braking surface, the drive reports.
Partially drilled dimpled holes dissipate heat without penetrating the brake pad surface and sacrificing brake disc strength. Slotted rotors also aid in the expulsion of built up brake dust, significantly more so than a drilled rotor. Drilled rotors’ holes, combined with the vents, let dust and hot gases escape more easily, carthrottle explains.
