Pros and Cons - Upgrading to Performance Brake Rotors

Upgrading to Performance Brake Rotors

Upgrading the brakes is usually one of the first things we do in order to increase the performance of our cars on the track. A good set of rotors and pads can make a night & day difference when pushing the limits. Brake rotors are an essential component of the braking system; they are responsible for providing the necessary friction to slow down and stop the vehicle. While stock brake rotors are typically adequate for most driving scenarios, enthusiasts like us often seek aftermarket options that offer improved performance and durability.

Lets talk about the different kind of performance rotors one would see as option to upgrade to. Drilled, slotted, and drilled & slotted rotors are some of the most common aftermarket brake rotor options. Lets discuss the technical differences between these types of rotor and the performance benefits they offer.

Drilled Rotors:

Drilled rotors are characterized by their perforated surface, which features a series of holes drilled into the rotor's surface. These holes serve two primary purposes. First, they aid in heat dissipation, which can help prevent brake fade in high-performance driving scenarios. Second, they allow gases and debris to escape from the brake pad's surface, helping to prevent glazing and improve brake pad bite.

However, drilled rotors do have some drawbacks. The holes in the rotor's surface can weaken the rotor, making it more prone to cracking and warping. Additionally, the holes can create stress risers, which can further contribute to cracking and failure.

Slotted Rotors:

Slotted rotors, as the name suggests, feature a series of slots machined into the rotor's surface. These slots serve a similar purpose to the holes in drilled rotors, allowing gases and debris to escape from the brake pad's surface and improving brake pad bite. Additionally, the slots provide additional surface area for the brake pad to make contact with, further improving braking performance.

Like drilled rotors, slotted rotors can aid in heat dissipation, helping to prevent brake fade. However, slotted rotors do not weaken the rotor's structure in the same way that drilled rotors do, making them a more durable option.

Drilled & Slotted Rotors:

Drilled & slotted brake rotors combine the benefits of both drilled and slotted rotors. The holes and slots work together to improve heat dissipation, increase braking performance, and provide a channel for dust, water, and gases to escape.

However, like drilled and slotted rotors, there are some downsides to drilled & slotted rotors. They can be more expensive than other types of rotors, and the holes and slots can create stress risers that can cause the rotor to crack under heavy use.

Which Type of Brake Rotor is Right for You? The type of brake rotor that is right for you depends on your driving style and needs. If you frequently drive in wet or dusty conditions, slotted or drilled & slotted rotors may be a good choice for you. If you are looking for improved heat dissipation and a unique look for your vehicle, drilled rotors may be the way to go. Either way you go, here at GR Performance Parts we got you covered.
