Slotted drilled rotors

All drilled and slotted rotors (except for hub rotor assemblies) are silver zinc plated to resist rust. With a direct OE fit and vane count, there are no special modifications needed on your car, truck or SUV. The drilled and slotted design is our most popular performance rotor for street and day track applications. Drilled and slotted rotors provide the looks and functionality of both cross- drilled rotors and slotted rotors combined. These beautifully machined cross drilled and slotted brake rotors include the same slotted design as the premium dimpled drilled and slotted brake rotors giving you incredible stopping power while keeping the dust away from your wheels.

The cross drilled holes are chamfered to eliminate cracking and move air from the disc surface while reducing surface temperature eliminating hot spots and warping. A drilled rotor has less metal content than a slotted rotor. The holes in the rotor help to get rid of excess water in the rotor when driving in the rain. When less metal is used in the construction of a rotor, it has less stopping power than a rotor with more metal content in its construction. Slotted rotors have more metal than a drilled rotor.

An these drilled and slotted rotors are backed by a 3-year warranty. USA Manufacturer - Free Shipping. Brake Pads, Brake Rotors , Brake Components and More.

These 2-piece rotors are available in slotted or cross- drilled designs, with directional slot pushing up to more air than OE rotors. Kits retain use of your factory brake calipers. There are several different types of rotors available for vehicles today: blanks, drilled , slotted , or drilled and slotted. Rotors , which are sometimes called discs, provide a point of contact for your brake pads when you engage the pedal to stop while driving.

Ideal for performance street driven cars, the new Sector Rotors come in drilled and slotted design, which provides improved stopping power along with reduced brake fade in the most. They are mostly just a cosmetic item. Rotors are not a place where you gain braking performance, nor lose it.

To upgrade performance you get a little change with pads, but not that much. If you want a bigger change you need larger brakes and better calipers, which is very expensive. In the slotted rotors, slots wipe the surface of the rotor forcing the gases to expel through the slots. The slots also greatly improve wet weather braking by preventing hydroplaning between the pad and rotor.

It’s a fact that venting the gas emitted by hot brake pads improves overall brake performance and helps minimize fade. Looking for brake parts to complete your classic car? The drilled holes in the rotors will be prone to stress-cracking, The combination of the drilled and slotted pattern does work great with heavier vehicles, especially vehicles that will be towing heavy loads. However, the slots can improve brake output by removing gas and dust that is trapped between the pad and rotor. This gas and dust reduces the friction force by preventing the pad from fully contacting the rotor.

Cross- drilled or slotted rotors do produce a strong visual appeal behind a modern open wheel, and they do have a performance edge when pad outgassing occurs. Outgassing occurs at extreme temperatures when the bonding agents that hold the pad material together break down into a gas form. StopTech drilled and slotted brake rotors are engineered to look good and perform at the same time! Performance brake kits, brake rotors , brake pads for your vehicle at wholesale prices. Blank or Smooth – As the name suggests, blank or smooth brake rotors have a smooth or plain surface, with no holes or markings in the metal.

Our Automobile Experts Provide Troubleshooting, Learning or Repairing Advice. To cool the rotor, manufacturers use a vented rotor, not a cross- drilled or slotted rotor. A cross- drilled or slotted rotor has less thermal mass and thus heats up faster and fades faster. The drilled - slotted combination is a popular performance option for both daily street and track applications.

But the holes in the face of a cross- drilled rotor also provide a direct cooling to the surface between the pad and disc by directly linking it to the interior cooling vanes of the rotor, increasing surface area and lowering brake temperatures. Often, one of the stated reasons for not going to drilled rotors is because of stones getting caught up in the holes. Drilled rotors are not generally allowed on the race track, unless they are OEM units.

Aftermarket drilled rotors are generally for show, not go!

They have come apart on the track! With top-level racing materials, the heat input is very rapid and the increase in localized cooling around the holes can cause issues. So slotted rotors were developed as a solution to a very specific problem associated with extremely aggressive friction material normally associated with racing,. Check Out Top Brands on eBay.

Fill Your Cart With Color Today! Sold in pairs, unless specified otherwise. Talon rotors are balanced with precision-milled slots allowing for a reduction in harmonic resonance issues, a cleaner pad surface, and debris evacuation. Most serious racers today have gotten away from cross- drilled rotors and now run slotted rotors or ones that use both slots and holes. Its cross- drilled design optimizes thermal efficiency, heat dissipation and strength, as well as improves wet braking.

Balance Vente and Drilled Steel Rotors. This process eliminates irregularities, causing the rotors to function very quietly and without vibration (or only the slightest vibration). Holes in the rotors maximize airflow across the braking surface, dissipating heat and letting brake dust escape. Dangerous cross drilled rotors. Second amateur rotor drilling companies may not take the time to ensure that their drill holes fall into the vent pockets in the rotor which are between the two faces of the brake rotor.

If these THROUGH DRILLED HOLES are drilled right through into the support vanes in the rotor core this will GREATLY weaken. While groove drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. Choose from EBC plain non drilled rotors or sport rotors in two choices – wide aperture GD Sport Rotors series for cooler running or newsuper silent Ultimax USR slotted rotor series.

When used with higher friction EBC Redstuff, Greenstuff or Yellowstuff brake pads these rotors will deliver better brakes.
