Description
SP Performance Diamond Slotted Brake Rotors perform like the slotted rotors, with the added bonus of the dimples. The slots on the brake rotor surface are used to expel the brake dust away from your braking surface and wheels, keeping the braking surface cooler. The Dimples, or Diamonds, on the surface of the rotor keep the braking surface cool, without the risk of forming stress cracks like the cross drilled rotors. All SP Performance Brake rotors are machine balanced and disc ground and meet OEM specification. The Diamond Slotted Brake rotors are direct replacements to your existing brake rotors and require no brake system modifications. All Slotted brake rotors come with your choice of coating for rust prevention. They are available in Silver Zinc Plating, Black Zinc Plating and Gray Zinc Coating.All Rotors are machined and plated to order by SP Performance employees.
Product Highlights
Directional Curved Slots: Helps increase brake pad bite, improves air circulation and cooling. The slots also vent gasses, reduce brake fade and stop brake hydroplaning in wet weather, reducing stopping distances.
Diamond Slots: Creates a recess to dampen expanding gasses that push against the brake pads and gives the rotors a very unique look.
Corrosion Resistant Finish: Corrosion resistant finishes give a clean look behind your wheels while preventing rust, corrosion and oxidation. Available in a Bright Silver Zinc Plating, Black Zinc Plating or Gray ZRC Paint.
Quality: Our brake discs are made using the finest quality castings that exceed OEM specifications. Designed with the use of CAD software and produced on CNC machines insures the highest quality and consistent performance.
Diamond slotting technology was originally developed by SP Performance. The diamond and slot design was created to maximize the performance while maintaining the structural integrity of the rotor. But don't be fooled, there are many imitators out there. If they are not manufactured by SP Performance then they're not true Diamond Slotted Rotors.
How Diamond Slotted Rotors Work:
Diamond Slotted brake rotors are used to move unwanted material and gasses away from the brake rotor and brake pad surfaces while keeping them as cool as possible.
The gasses are created by the repeated use of heavy braking, which causes a layer of brake dust and gasses to build up between the brake pad surface and the brake rotor surface. What this does is actually push the the brake pad away from the rotor surface. By adding the slots onto the surfaces of the brake rotor, this allows those gasses to escape which in turn creates a solid bite between the brake pad to brake rotor. By allowing the gasses to escape, the brake rotor and pad surface stay cooler which will help eliminate brake fade.

Beatiful Functional Upgrade
I put four of these on my 2019 Ram 1500 and they are fantastic! Breaking performance is fantastic and they look bad ass! No rust so far after a year on my truck.

2019 LT - Dsteady
Lol to the ppl thinking they Stay black
The coating is an anti rust coating the coating is meant to come off where the pads contact leaving the coating to prevent rust. If you think the rotors are black metal then you need to do your research. I worked with sp performance and there brakes are awesome quality they are g3000 iron same as brembo and top brake manufacturers and they offer diff coatings and slot and drilled patterns. Plus the rotors are not garbage from China they are manufactured in north America. Also if the coating melted and burned off then you clearly did not break them in an heat cycle them properly.

sloppy coating does not look like picture and clogged up all of the slots
I spent $1000 for good brakes on my truck. These looked very good to me in the picture. I assumed the black coating was something fancy. The coating is actually just PAINT. once installed and test drove. I realized that the slots are completely clogged with melted paint. i appreciate the paint on the hub of the rotor to prevent rust. But painting the pad face has completely clogged my rotor slots to the point that i need to remove them and use brake cleaner to clean the slots. VERY UNHAPPY. this was not described in the description. not instructions said that I should remove the black coating before installation. overall the rotors look nice and think. but this coating is causing me to do 2 brake jobs now. I recommend buying a NON coated rotor and painting to your liking. it will save you a lot of HASSLE.

These are direct fit replacements with slots machined into the faces of the rotors for dust/heat dispersal.

Joke!
Do not buy these if you are looking for black rotors. Not only did I have to wait a month to receive mine. When I did, I opened the box and it smelt like paint. Ended up putting them on. Not even 5 seconds of backing out of the driveway. The black on all 4 rotors was gone and stuck under the new pads.

Fits good but has a flaw
The black wears off the first time the pads touch the rotors. Otherwise they look and performance nicely.

Not zinc plated
Don’t waste your money or time on these or any “zinc plated rotors” from these guys. Save your money and order Regular rotors. This “coating” is just paint that comes right off as soon as you hit it with break cleaner and is just a sad excuse for this company to upsell these for $100 more.
