Do Performance Brake Rotors Have Better Cooling?
Slotted Disc Brake Rotors Without question, brakes are the most powerful system on your vehicle.
Your factory brakes provide ample stopping power for your casual commute or the occasional unforeseen panic stop, but for the performance-minded enthusiast, an upgraded set of drilled or slotted rotors is the better choice.
So what exactly are the differences between drilled vs.
Here, we discuss the benefits and drawbacks of each, so you can make your own informed decision.
Smooth Rotors Smooth Brake Rotors A premium set And casino journal and slot management opinion smooth rotors provides more than enough stopping power under normal driving conditions.
They provide the most surface area vs.
The absence of slots or drill holes allows smooth rotors to maintain maximum structural integrity, making them suitable for moderate track use when paired with performance brake pads and high-boiling point brake fluid.
There are several varieties available, from direct replacement to high-quality zinc-coated rotors, to fight off surface rust and maintain their like-new appearance for miles and miles.
Slotted Rotors Slotted Brake Rotors Slotted rotors, as the name implies, have grooves cut along the face of the rotor where the pad makes contact.
This is because under repeated heavy braking, as the temperature of your brake system increases, a layer of gas and dust forms between the pad and rotor from the material continue reading caused by friction.
The slots in the rotor allow an escape route for the built-up gases.
The venting provided by slotted rotors is one of the main ways to combat brake fade and maintain consistent stopping power, lap after lap.
Cross Drilled Rotors Cross Drilled Brake Rotors Cross-drilled brake rotors look undeniably cool peeking out from behind a set of flashy wheels, and they keep your brakes the same way — cool.
In the early days of racing, drilled rotors were an effective way of venting the layer drilled slotted rotors pros and cons gas and dust that inevitably builds up between asbestos brake pads and the rotor under repeated, hard braking.
However, as technology and brake pad materials have progressed, outgassing has become less and less of an issue.
These days, while they still look great and perform well, the drill holes are more for aesthetic reasons than anything else.
For performance driving, slotted rotors have become the preferred choice because cross drilled rotors are more prone to stress cracking under extreme use.
On the street, however, the temperatures your brakes encounter never even come close to the levels they do on the track.
While still not ideal for the abuse they would suffer on a racetrack i.
The heavier the vehicle, the more energy is needed to slow it to a safe and reliable stop.
Brakes convert kinetic energy motion into heat energy, and heavier vehicles invariably generate more heat in their braking systems.
So a rotor that runs cooler cross-drilled combined with one that maintains a clean contact surface between itself and the brake pad slottedwhen not pushed beyond its thermal threshold, can provide an extra bit of security and durability.
Remember, the drilled slotted rotors pros and cons of the game is maintaining consistent stopping power every time you hit the brakes.
A set of cross-drilled and slotted rotors can give you additional peace of mind by keeping temperatures down and the rotor face clean.
Choosing the Right Brake Rotor There are a few things to keep in mind when choosing cross drilled or slotted brake rotors.
It just comes down to personal preference of which style you prefer.
Their purpose is to dissipate heat and gases to combat brake fade and provide consistent stops after prolonged abuse.
In order to take a sizeable chunk out of your stopping distances, a set of sticky tires and dedicated high performance brake pads are the recommended upgrades.
For track driving, slotted rotors are the preferred choice due to their ability to vent gases without weakening their structure.
For daily link, any of the above provide more than enough stopping power.

Pros and Cons of Cross-Drilled and Slotted Rotors A recent trend in the sports car/Truck market is the use of cross-drilled or slotted rotors. You see them on all kinds of cars & Trucks today, and while they may look nice, few people know the benefits to using them.
