Mountain Pass Performance - 2-Piece Front Rotors- Tesla Model S/Model X
If you haven’t already seen our 400mm Plaid Big Brake kit, we suggest you check that out first. The OE replacement rotors here are suggested for those who want to use OEM 19″ wheels or can otherwise not fit our 400mm upgrade. The 400mm BBK is only a bit more expensive and offers a significant improvement in terms of brake cooling and aesthetics!
If our 400mm kit is too large for your wheels, we have your solution – OE-sized replacements!
- Lightweight, 4.8lbs lighter per rotor
- OE Diameter for those wanting to fit OE sized 19″ wheels
- Visually stunning two-piece rotor
- Aluminum anodized hat made from US-Sourced 6061-T6
- Directional rotors with curved vanes for optimal cooling
- Made in the USA
- Rotors made by a leading brake supplier with winning experience in the highest level of motorsport.
All brake systems can only remove heat via the rotor or external ducting. No matter how large the caliper and pads you put on your car – the ultimate limit comes from the thermal equilibrium – how much heat you put into the brakes versus how much heat the brakes are able to shed. With a low-drag, 1000hp car, you can imagine that there’s a LOT of energy that can be put into these brakes.
Our rotors use curved vanes which turn the rotor into an air pump – the faster the wheel rotates, the more cool air is sucked from the inside of the rotor and pumped outwards through the vanes – which increases the cooling capacity of the rotor far above what a standard vane rotor would have. All motorsport and racing rotors use directional curved vanes, and that is the critical difference between the OEM rotors that allow this kit to shed so much more heat.
Unlike some 2-Piece rotors, these rotors will never make any noise or disc rattle, and by using an aluminum hat we are able to shed a significant amount of zero value weight while looking incredible. It’s win-win. In addition, these rotors have the OEM pad annulus (pad height) so you are not restricted to one pad supplier. Any aftermarket pads for the Tesla Model S Plaid will be compatible with our discs.
These rotors are extremely simple to install, and as they are OE sized, no trimming or removal of the OEM brake dust shield is required. However, the removal of the dust shield significantly aids with brake cooling.
One of the things we’ve always tried to do at MPP was to provide quantitative proof of the results and performance we claim. We always talk about our motorsport background, but by sharing some of the real development we do we aim to earn your trust and show just how working in professional motorsports is benefiting the products we offer. Below are test results from our 400mm BBK. The results are of course better than you can expect with the OE-sized 380mm rotor, but are still shown for reference of how much the curved vane rotors help with cooling.
Below you’ll find the results of brake rotor surface temperature as measured by multi-channel IR brake temperature sensors. During this test, we equipped the car with the 400MM BBK on the left corner, while leaving the OEM 380mm rotor on the right. To keep the variables under control, we ensured that brake pads, tires, and tire pressures were equal from side to side. The data was logged with the same MoTeC ECU that we are also using to emulate the OEM Tesla Suspension controller, and as a result, we even display the OEM brake temperatures on the Suspension UI!
Incredibly the OEM rotor got up to an alarming 900degC – so hot that it was glowing bright red even in the daylight sun. The MPP rotor reached only 800degC on the outside tip of the disc. Notice that the outer edge of the disc runs hotter than the inside on the MPP rotor – evidence that the air being pumped through the rotor is having a significant impact on cooling – as the cool air enters from the center of the disc (the inside) and pumps out radially. Once the OEM rotor is heat-soaked, it sheds its heat much more slowly than the MPP rotor – whereas the MPP rotor removes more heat and is cooler at the application of the brakes in the next braking zone. Additionally, as the inside of the rotor is cooler, the surface temperature cools faster as it is not as heat soaked as the OEM rotor.
These rotors are zinc coated, to help reduce oxidization. Note that these rotors, like all rotors, will oxidize over time, especially if not in use or if driven on salt-covered roads. A few normal brake applications will clear the rotors of any surface rust that has developed.
Kit includes the following:
- (2) Rotor rings and rotor hats assembled and ready to be installed on the car. They are directional so be sure to install them on the correct side!
