Back from a bike ride where it occurred to me that I too was disappointed with (what appears to be) uprated front brakes. I did not do any high energy braking for reasons explained above but what little braking I did left me surprised with the lack of initial grip followed by the feeling that the pads were gliding across the rotor surface.
I've felt this before with green brakes that needed bedding. Race teams send their rotors and pads out to a brake dyno to have both components properly bedded in a controlled repeatable environment. They do not want to use precious track time to do this and simply do not trust professional drivers to do it correctly consistently.
These are obsolete Brembo rotors purchased from a team that had moved to Performance Friction. Note that they all look used inclusive of heat sensitive paint which has reacted. They are new, just bedded and ready for track use.
I normally do both mine and my wife's S' when we take delivery as they always feel a bit green. The Plaid's are VERY green and, if you tried any high energy braking before bedding, you would certainly glaze the rotors and pads which dramatically reduces braking performance. Tesla rotors readily surface corrode with just a little water. If this is still the case with glazing, this might give people a chance to recover. If not, we used to have to take the rotors and pads off, clean to bare metal and fresh pad with an abrasive wheel then re-try to properly bed them.
I've typically turned off re-gen to bed S pads in the past. It will be interesting to try and do it accounting for re-gen this time around as there is no way to turn it off. Another forum member has pointed out some differences in the rear calipers. If Tesla is doing something with torque vectoring under braking to increase stability it may be even more difficult trying to get the right amount of heat/energy into the fronts and the rears without overdoing either.
Fun stuff to keep a nerd busy.
All off topic. This has been my home for the last 8 weeks but I am happy to move this stuff to another thread.
