Brake rotors come in different types. Before you can purchase, understand each of their different types and what sets them apart:
1) Drilled Rotors are for general use and street performance. These rotors have holes that help release the water and are best in wet and rainy conditions. However, they can wear unevenly when used in racing vehicles due to the heat and temperature extremes of a race. While this does not really impact their performance, it can affect the vehicle aesthetic Sensitive drivers may prefer to select a different style of brake rotor or else change out their rotors more often.
2) Slotted rotors have slots that shave off any brake dust and other particles. They are still best for street performance, along for Autocross/Track, Towing/Hauling, and Off-Road vehicles. This style delivers improves its consistency to every stop by reducing the friction in the brake pads. The only disadvantage is that they tend to have a shorter life compared with other types. When the driver comes to a stop from a high speed, a rumble can be felt from the rotors. They will still perform safely but the noise you may be unpleasant.
3) Drilled & Slotted Rotors offer the benefits of drilled and slotted rotors together. These newer brake rotors are starting to appear on some luxury cars, including Mercedes and BMW. On another hand, if you are looking to use it for performance racing, then these rotors are not the right one since the drilling makes them vulnerable to cracking.
4) Blank (OEM) Brake Rotors are installed for maximum effectiveness across different driving conditions. Endurance racers who need brake pads that can hold up through a long race, these smooth or blank brake rotors can work very well for their needs. They tend to be the longest lasting overall, while also produce very little dust and are quiet to operate.
If you seek a rotor for a specific performance need, you now have the information that you need to be able to select the best brake rotors for your ride. Just always pay attention to how your vehicle drives and how it brakes. As young brake system begins to age, plan ahead and order replacement parts so you can install new brake pads and rotors before your existing ones fail.
