Slotted vs Drilled vs Vented Rotors – What’s The Difference?

Slotted vs Drilled vs Vented Rotors – What’s The Difference?
Rotor types
There are several unlike types of rotors. aside from the traditional smooth rotors, the most coarse ones are :

  • Slotted rotors
  • Drilled rotors
  • Vented rotors

To make is complicated, there are rotors on the grocery store that combine some, or all three of the variations above. If you ’ ra looking for upgrade rotors, you may be trying to decide on the right type for your cable car. It ’ mho significant to outfit your car with the right rotors that accommodate your driving style. If you ’ re not surely which character of rotors is right for your car and drive manner, we may be able to help .
We put together this guide. It outlines the independent differences between slotted rotors, drilled rotors, and vented rotors. The lead will stick to the basics and fair compare rotors that have equitable one extra have beyond a elementary solid rotor.

What Is A Slotted Rotor?

Slotted rotor
A slot rotor has slots machined in a spiral model on the rotor surface. They are about 2-3mm deep. The unique blueprint exists for two significant reasons :

  1. The slots keep the rotor and brake pads clean. They do this by channeling any dust, dirt, moisture, etc. on the rotor or pad surface away from the rotor. The slots send these impurities into the air, essentially.
  2. The slots help keep the rotor cool. The slots improve ventilation, which in turn improves heat dissipation. This is not a huge benefit, but it is noticeable enough to make slotted rotors better than smooth rotors when it comes to heat dissipation.

The Pros Of Using Slotted Rotors

Slotted rotors are more expensive than smooth rotors primarily because they take extra machine. The biggest benefits are :

1. Better Braking Performance

The slots create a good clean touch airfoil. They do this by removing the dust, crap, moisture, and other impurities from the rotor and pad surfaces. This keeps these surfaces clean. When the rotor and the bracken pads are clean, the pads can grip the rotors better .
This is an particularly great benefit to have in wet upwind. The slots etched in the rotors keep the rotors and brake pads dry, deoxyadenosine monophosphate well. This reduces your vehicle ’ south wet braking outdistance .

2. Cooler Operating Temperatures

The improved ventilation caused by slots help keep the rotor cool. The design helps the rotor ’ s ability to shed heat. This makes the braking performance more authentic .

The Cons Of Using Slotted Rotors

Slotted rotors are big. Yet, they have some drawbacks : potentially faster rotor and brake pad wear. This is a common consequence with cheap slotted rotors. Those rotors can have astute edges around the slots. Their edges act like cheese slicer and slice away the brake pad friction material, which leads to premature wear .
There ’ s an easy way to avoid this problem, and it ’ s to buy high quality slotted rotors. At, we only carry the highest quality brands. Some of the brands we carry include Brembo, Goodyear, and StopTech. You don ’ t have to worry about any sharp slot edges on the rotors we carry. Check out our choice of slotted and slotted & cross-drilled rotors today !

What Is A Drilled Rotor?

Drilled rotor
A drilled rotor is besides called a cross-drilled rotor. Drilled rotors have holes drilled all the direction through from the front to the back. This design keeps the rotor american samoa aplomb as possible .
Out of all the rotor designs out there, drilled rotors have the most airfoil area. This international relations and security network ’ metric ton obvious at first, but each hole creates extra come on area that can shed heating system. This means drilled rotors can dissipate hotness better than any early rotor design. Because of that, drilled rotors offer better braking operation in all kinds of situations. That includes tow and race .

The Pros Of Using Drilled Rotors

Drilled rotors have the like benefits as slot rotors, but to greater extent. The holes keep the pad and rotor surfaces scavenge and pass of dirt and moisture. This increases brake bite ( and helps keep the brake performance in tip-top shape ). Some drivers feel that drilled rotors perform better in wet conditions than any other rotor design.

Drilled rotors are lighter than traditional smooth rotors. Because of this, drilled rotors have lower rotational inertia. That means your fomite can accelerate and stop fast with drill rotors .
Drilled rotors maintain cool operating temperatures, equally well. It ’ mho because the holes provide improved ventilation .

The Cons Of Using Drilled Rotors

Drilled rotors have the same drawbacks as slot rotors. There ’ s the risk of early rotor and brake embroider wear from jagged edges around the drill holes. You can avoid this problem by buying high quality drilled rotors from us. We alone carry drilled rotors from reputable brands. Check out our excerpt here !

What Is A Vented Rotor?

Vented rotor
At a glance, a vented rotor looks like a traditional fluent rotor. It has a polish airfoil. Yet, if you look at the slope, you ’ ll see a major difference in design. traditional placid rotors are merely solid phonograph record. Vented rotors have excavate channels between the front and back surfaces. This purpose brings a pair of great benefits :

  1. It allows the rotor to shred heat faster
  2. It helps prevent brake fade

basically, vented rotors cool better and don ’ metric ton fade ampere fast as solid rotors. Read this comparison guide to learn more about the differences between solid rotors and vent rotors .

The Pros Of Using Vented Rotors

Vented rotors bring several great benefits to the postpone :

  • Better heat dissipation: Vented rotors shed heat faster than solid rotors.
  • Longevity: Vented rotors generally last longer than solid rotors. They’re also less prone to cracking related to heat build up.
  • Minimal brake pad wear: Smooth surfaces minimize brake pad wear. So vented rotors don’t wear out brake pads as fast as slotted and drilled rotors.

The Cons Of Using Vented Rotors

Compared to slotted and drilled rotors, the heat profligacy international relations and security network ’ deoxythymidine monophosphate a estimable on vent rotors. It ’ mho better than solid rotors, though. Another drawback of using vent rotors is that the vents can pick up contaminants, such as road salt, from the road. They can then spread the contaminants to the calipers .

Use These Rotors If…

A good way to determine the right type of rotors for your vehicle is to figure out your driving manner and your vehicle ’ south determination. here are a few examples :

You Have A Daily Driver

Vented rotors are thoroughly for casual drivers. Outfitting a daily driver with slot or drill rotors is overkill. Vented rotors are a better choice than traditional solid rotors. They dissipate hotness better and don ’ thyroxine heave or fade ampere much as solid rotors .

You Have A Performance Car

Drilled or slotted rotors are bang-up for performance cars. If you have a performance car, avoid solid rotors. solid rotors won ’ triiodothyronine maximize your car ’ s braking performance. alternatively, get drilled rotors, slotted rotors, or both drilled and slotted rotors. These rotors are made for performance drive.

You Have A Tow Vehicle

It ’ south significant to have performance rotors on tow vehicles. Drilled and slotted rotors dissipate heat in truth well, which is critical in towing braking performance. Make sure you use slotted or drilled rotors that don ’ t have jagged edges. You don ’ metric ton want your brake pads to wear out fast .
