Which Way Do the Slots Go on Slotted Rotors?

If you are a car enthusiast or a mechanic, you must have come across slotted rotors. Slotted rotors are designed to provide better performance than standard rotors.

The slots on the rotor help to dissipate heat, improve stopping power, and reduce brake fade. However, many people are often confused about the direction of the slots on slotted rotors. In this article, we will discuss which way do the slots go on slotted rotors.

Before we dive into the direction of the slots on slotted rotors, let’s first understand what slotted rotors are and how they work.

Slotted Rotors:

A slotted rotor is a type of brake rotor that has slots machined into its surface. These slots run perpendicular to the direction of rotation and are cut into the rotor’s surface between each pair of vanes.

The primary purpose of these slots is to allow gases and heat generated during braking to escape from between the pad and rotor surfaces. This helps keep the brakes cool and reduces brake fade.

Another benefit of slotted rotors is that they can improve braking performance by providing more bite or friction between the pads and rotor. The slots also help remove debris from between the pads and rotor surfaces, ensuring consistent braking performance.

So which way do the slots go on slotted rotors?

There is some debate among mechanics as to which way slotted rotors should be installed – with the slots facing towards or away from the car’s centerline.

Some argue that installing them with their “leading edge” facing forward (towards where you’re headed) offers better cooling because air flows over them more efficiently as they rotate. This makes sense because air will naturally flow over a surface in one direction easier than it would if it were moving against it.

Others argue that installing them with their “trailing edge” facing forward (away from where you’re headed) offers better performance because it provides better initial bite or friction between the pads and rotor. This makes sense because the leading edge of the slot would be in contact with the pad first, providing more friction.

Ultimately, there is no definitive answer to this question. It largely depends on personal preference and driving style. Some drivers may prefer the added cooling benefits that come with installing slotted rotors with their leading edge facing forward, while others may prioritize initial bite and prefer installing them with their trailing edge facing forward.

Conclusion:

Slotted rotors are an excellent upgrade for anyone looking to improve their braking performance. They offer improved cooling, reduced brake fade, and better initial bite.

When it comes to which way do the slots go on slotted rotors, there is no right or wrong answer. Ultimately, what matters most is that you install your slotted rotors correctly and maintain them properly to ensure they provide optimal performance for years to come.

So next time you’re considering installing slotted rotors on your car, make sure you weigh the benefits of each installation method against your driving style and choose the option that best suits your needs!
