I would say without a doubt, this is the most track-focused kit currently available. Overall, they check all the boxes as far as thermals/fade, noise, and immediacy are concerned. I rarely drive my Model 3 except to go to, on, and from the track, so it isn’t a concern for me.

Fortunately, if you are daily driving the car, they are easily removable. After comparing before and after, and against my wife’s car, it appears that leaving these in place reduces range by about 8% on the street under relaxed driving. Any amount of brake force now causes excessive squeaking, while the AP Kit has always been and continues to be silent.įor those who are wondering, I chose to leave the Anti-Knockback Springs in place. One interesting note, the Carbotechs have become incredibly loud on my wife’s car. I’ve owned several BBK’s, and driven hundreds of cars, and none of them had brakes that felt this good. It eliminates the “play” in the brake pedal, and the lightest push of the brake pedal engages the pads. It is also worth mentioning that this kit completely changes the feel of the brakes.

I did not have any fade with the AP kit at any time. The stock caliper setup would get squishy/mushy and I had some pretty notable brake fade a few times coming into Turn 1. The AP kit was certainly more consistent than the stock caliper setup. The hottest the AP Kit got was about 1050f, compared to about 1,250f on the stock calipers with Carbotech RP2 pads (this was in my wife's car with stock rotors). On average, they ran 23% cooler than the stock caliper setup. However, with the AP kit you are gaining a considerable increase in braking stiffness, immediacy, feel, thermal capacity, and pad options.Īs far as thermals go, I doubt anyone could overheat the AP Kit brakes with expected track use. As you can see, the total weight of the stock brake setup and the AP kit are within 1lb of each other.
