With so many different types of brake rotors on the market today, it can be tough to make a decision on what to buy for your vehicle. Below you will find a breakdown of different types to assist you in finding which type is right for your application.
Plain, Solid or Vented Rotors
Vented means there are cooling fins between two layers of iron that you see as the disk on the brake rotors. Solid rotors are thinner and have only one disk of iron as a braking surface. There isn't usually a choice between the two types, it's a matter of what the vehicle needs. These are great for all applications, whether it's a daily driver or a weekend auto.
High Carbon Plain Rotors
Centric Plain 125 High Carbon Series are a heavy-duty, longer lasting plain rotor that's ideal in this category.
Cryogenically treated rotors undergo a very slow transition down to 300 degrees below zero (Fahrenheit) and a slow transition back up to room temperature. This forms stronger bonds in the iron and makes the rotors stronger and more durable.
Contrary to popular belief, drilled and slotted rotors are not recommended for track use, and are predominantly for aesthetic purposes. While drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they're not designed to withstand the extreme temperatures that are produced on the racetrack. So if you like the looks of drilled and slotted rotors, by all means, get a set! However, if you're looking for something for high-speed track use, avoid these because they will crack easily under extreme heat. The milling done on drilled and slotted rotors actually removes some of the metal on the rotor that is used to absorb and dissipate heat, so unless you have a big brake kit upgrade to make up for the lost material, the drilled and slotted rotors are actually a little less effective than a plain rotor.
