Even if car parts aren’t your thing, you can tell these apart easily. If you’re new to car maintenance or haven’t bought brake parts before, no worries—knowing what these look like will help you figure out what’s on your car now.

Drilled Only Rotors

Drilled rotors, easily spotted by their distinctive pattern of holes, are a top choice for street performance and are especially handy in consistently wet conditions. These rotors are a popular choice among performance enthusiasts and those who prioritize aesthetics along with functionality.

Pros:

Drilled rotors are a great choice if you live in a rainy area. They handle wet conditions well, last a long time, and provide more friction in wet roads than slotted rotors. This is because the holes in the rotor allow water to escape, drying the brake system when it’s wet, thus better brake performance when it’s wet outside.

Cons:

Drilled rotors have some downsides despite their benefits. They can wear unevenly and may develop cracks under high heat, like during races. Over time, they can also look strange due to their wear pattern, especially if the holes aren’t staggered. This doesn’t affect their performance, but might bother some drivers.

They’re not suitable for race cars due to their inability to handle repeated heating and cooling cycles. However, they’re just fine for regular street driving.

Slotted Only Rotors

Slotted rotors are ideal for Street Performance, Autocross/Track, Towing/Hauling, and Off-Road driving. If you live in an area with irregular landscapes and uneven terrain, slotted rotors are the best choice for you.

Pros:

Slotted rotors are an excellent choice for vehicles that are frequently driven in challenging terrains, or for those who often haul or tow heavy loads. They are particularly effective in these conditions due to their design which allows for efficient heat dissipation and reduced brake fade, which in turn provides a more responsive and prompt stop.

This style of brake rotor delivers improved consistency with every stop, by creating an escape route for the gasses and heat that are generated during braking. You can rely on these pads to deliver effective braking even in heavy duty vehicles.

Cons:

While slotted brake rotors have their benefits, they also come with a few downsides. They typically don’t last as long as other brake rotor types, and they can potentially cause your brake pads to wear out faster. When you’re slowing down from high speeds, you might feel a shaking sensation from the rotors. This doesn’t impact their performance, but the noise could be off-putting for some drivers.

Cons:

While drilled & slotted rotors offer a variety of benefits, they are not recommended for performance racing since the drilling makes them vulnerable to cracking. This is due to the extreme heat and pressure conditions that racing rotors are subjected to. When exposed to these conditions, the drilled holes can become stress points where cracks can begin to form. Over time, these cracks can grow and lead to rotor failure.

Blank Rotors

Blank Rotors are the best choice for normal daily driving in standard terrains and consistent weather conditions. On the contrary, blank rotors are also the best choice when doing extremely aggressive driving such as racing.

Pros:

If your driving routine is standard, such as commuting to work or going grocery shopping, and you don’t drive aggressively or go to uneven terrains or do hauling, plus you value a quiet braking system, then smooth rotors could be your ideal choice.

On the other hand, another pro of blank rotors is that despite being the ideal choice for everyday commuting, also excel in racing environments. The lack of drilled holes or slots means there are no weak points where cracks can form under the extreme heat and pressure conditions of racing.

This solid surface can handle the intense heat generated during high-speed braking better than its drilled or slotted counterparts. Furthermore, the smooth surface of blank rotors provides the maximum amount of contact area between the rotor and brake pad, allowing for more consistent braking performance.

Cons:

While there are few drawbacks to using blank rotors, some drivers might wrongly assume that drilled or slotted rotors are specifically the best. This isn’t always the case; the best rotor for you largely depends on your driving habits and the kind of stopping power you’re looking for. So, don’t be swayed by common misconceptions—choose the brake rotor that aligns with your vehicle’s use and your personal driving style.

If the brake rotor you have works fine, just get the same type when you replace it. If you need a rotor for something specific, like rainy days or racing, you’re all set to pick the right one for your car.
