Drilled vs Slotted Rotors: Infiniti G Series

What’s better for your car? Is it drilled rotors or slotted rotors? In the automotive world, there’s a bit of debate around this. In this blog, which forms part of our drilled vs slotted series, we’ll determine whether drilled rotors are best for the Nissan Infiniti G Series, or whether slotted rotors take the win.

What’s so special about the Nissan Infiniti G-Series?

The Infiniti G Series is Nissan’s version of a compact, executive car, and has won multiple awards. First released in the United States in 1990, new models continued to develop until 2016. With the introduction of big names like the Skyline and the 370z, Nissan stopped producing the Infiniti G Series.

What type of brakes are there?

There are many different types of brakes on the market. When it comes to rotors, there are blank rotors, slotted rotors, drilled rotors, and drilled and slotted ones. You can easily identify them by their names, with blank rotors having no drilled or slotted grooves on their face, slotted rotors having slotted grooves, drilled rotors having drilled holes, and drilled and slotted brakes having both grooves and holes on them.

What are drilled rotors?

Besides having drilled holes on their face, drilled rotors have certain features that make them an attractive choice. Drilled rotors work better under rainy conditions because the holes allow the water to evaporate quickly, allowing the rotors to have a better grip. With their ability to evaporate more water, drilled rotors allow the brake system to have improved performance and  a better bite. 

Drilled rotors are sometimes unpopular in race tracks, as the drilled holes can sometimes give way to cracks and fractures. These cracks are due to high temperatures at high speeds. Keep this in mind if you are looking to use drilled rotors for the tracks.

What are slotted rotors?

Slotted rotors have slotted grooves that act as “blades.” These blades shave away brake pad material and other dust particles that may come in contact with the rotor and brake pad. Shaving these away helps the brake perform better on the track, where high speeds are the norm. However, keep in mind that all the shaving may require changing your pads more frequently.

These rotors work very well with cars that see the racetrack often, where performance is highly valued and appreciated. If you are a normal daily driver, you may want to steer clear due to the maintenance cost.

Which one is better for the Infiniti G Series?

If your Infiniti brake pads and rotors are due for replacement, then you’ve come to the right place. As mentioned, different brake rotors are geared for different types of usage. 

If you use, for example, your g37 on the tracks more than for daily use, you might want to purchase slotted Infiniti g37 OEM rotors. Racing with your car means you value performance more than longevity.

However, if you use your g35 for a more daily routine, then purchasing drilled Infiniti g35 rotors might be the best move for you. You don’t need that slight advantage in performance, especially if you’d have to sacrifice longevity for it.
