285/35R20 Bridgestone RE71RS
Stock 2024 Model Y suspension on Eibach springs

Trying out different track mode settings.
0% regen (min)
-10% stability (min)
35% front/65% rear bias

Motor felt consistent for power output over 3 minutes with regen turned off but brakes got a lot hotter. In a later run I tried 50% regen and it seemed to have a decent balance. With this torque split the rear motor does show to heat up faster than the front but it didn't get to an overheat range even in a later/longer session. 

It's a matter of finding what works for the car so that the brakes don't get too hot (for obvious reasons) and the motor/battery doesn't overheat where it cuts power. 

Overall the body control on this setup is quite sloppy, with -0.1 degrees of total front toe out the car still has a very delayed steering response and a lot of roll. This makes going down the corkscrew and T6/7 chicane very challenging as the car takes a while to settle. Coilovers and more front camber would do this car wonders. Rear suspension geometry feels decent at this pace but the front end is floppy. This car was designed for frunk and motor space and not chassis rigidity and this is evident when you start to push harder.

We ran EBC bluestuff front pads as they were the only things quickly available, but the rear was running the OEM pads. The OEM pads cannot handle heat at all and under braking will put out a big puff of smoke and just disintegrate/smear. A big brake kit and rear pads would go a long way as it would reduce the need for regen and help the car run for longer.

In terms of battery, a 10 minute session used about 20% battery
