To me, the first concern to address is the brakes. While not needed for a leisurely day out at the track, or your first event, they quickly become a weak-point if you are pushing it. That being said, I personally would not recommend BBK’s, as they are generally expensive and overkill. Regenerative braking in my experience does help with heat dissipation and brake component life significantly. A nice set of rotors, and (in particular) pads in combination with high performance brake fluid is more than suffice for most people. For Performance Model 3’s the stock rotors are enough if you don’t want to spend money on the upgraded rotors, and they are cheap to replace.
