The Original Tesla Model 3 Big Brake Kit
During our testing in California we overheated the Model 3’s brakes while enjoying a spirited drive downhill on Page Mill Rd. We almost completely lost braking power! For that reason we’ve named this brake kit the Page Mill 365mm Big Brake Kit for Tesla Model 3! This BBK upgrades the rotor size from the OE’s tiny 320mm to 365mm, and the thickness goes up from 25mm to 26mm. This is a MASSIVE difference in rotor size! As a result the thermal ceiling, even on stock brake pads goes up dramatically.
The Model 3 struggles with braking performance. The main source of the problem is overheating the front pads. Larger rotors dissipate much more heat, and that is why you find large rotors on just about every sports car in the world. No matter what kind of brake pad you put on you still need a way to shed heat. It is almost more important when using a street friendly brake pad to have a large rotor, as you want that rotor to run at the lowest possible temperature to keep from overheating the mild pad.
By moving from a single piece iron rotor to a two-piece aluminum hat and iron rotor ring, we reduced the weight of the brakes, despite the significant increase in size! This kit reuses the OEM caliper, which is notable as the caliper is designed to have very low brake drag. This plays an important roll in the Model 3’s outstanding energy efficiency. These rotors also have curved vanes, the internal air passages in the rotor. Because the vanes are curved they act as an air pump and dramatically increase the airflow and cooling of the disc at speed.
We performed a test using our MoTeC C125 dash logger and some IZZE CAN-Based IR Brake Temperature sensors to prove the impressive difference that this brake kit provides over the factory rotors. See below: almost a 100C difference in rotor temperature. It is clear in this data that after only a few hard braking applications that the OE rotor has gone thermal, while the MPP rotor still has plenty left in reserve.
Our big brake kit, especially when combined with higher friction, higher temp brake pads, is the ideal solution for the road car that likes to see the track. It solves the problems of at the track brake overheating, without the compromise of big brake kit costs or inefficiency on the road. Even for cars that don’t hit the track, as we saw with our spirited driving, the OEM pads are designed to be environmentally friendly. As a result, they have a very low maximum temperature before they fade. A larger rotor with enhanced cooling will delay that pad fade for as long as possible. Not to mention, they look awesome behind your wheels!

You can read all about our experience with the brake kit here from our GridLife competition event. Ours was the first Model 3 in competition globally, and these rotors made all the difference in the world! Even with racing brake fluid, we boiled the fluid after 3 laps with the OEM rotors. There simply wasn’t enough thermal mass and airflow with the standard discs.
You can also watch a review from Speed Academy of our Model 3 with the brakes, among other parts, here. We had a great time filming this episode!
Our big brake kit installs in less than one hour and is fully reversible. The factory caliper’s brake line does not need to be disconnected. A bracket is simply installed with supplied hardware. Then, the new rotor is slipped on after the removal of the OE dust shield (dust shield removes very quickly, does not require hub removal). Finally, the caliper is bolted to the new bracket. We install and remove this rotor for every track day as we’re currently driving primarily on 18″ wheels!
This kit includes the following:
- (2) Rotor rings and rotor hats assembled and ready to install on the car. They are directional so be sure to install them on the correct side!
- (2) Caliper brackets
- (4) Caliper bracket bolts
Note: This brake kit will NOT work with 18″ wheels. 19″ wheels or larger are required.

I’ve used this kit for a little over a year now on and off the track at Buttonwillow and Laguna Seca in my Dual Motor LR. It’s a high quality kit that’s track proven. It’s a must have if you intend to flog your Model 3.

Great braking improvement, better looks is a plus. I highly recommend these. I’m about to order another one for my wife’s M3.
Fantastic reliable, fade-free performance session after session. Looks as good as it works! This brake kit is a must-have for tracking the Model 3.
With such a heavy car and quick acceleration, the brakes are lacking when you want to push it. Upgrading to better pads and fluids are a must for spirited driving and track use. This big brake kit is a marked improvement in heat dissipation. No issues with fading pushing this hog around the track. I use Endless EX90 pads and never faded and always had great bite for the entire track day.
These will fit some 18″ wheels as well. Great installation instructions and an amazing upgrade!
