Using the photos supplied in the configurator, it appears the performance model suspension sits maybe ~20-25mm lower (best guess) than all other configurations. The dual-motor Model S on coil suspension only loses 0.2" (5mm) ground clearance when adding the front motor per the users manual, and this is clearly more than that in the Model 3. I noticed this thanks to the reddit thread here that lets you easily compare all configs using Tesla sourced images: Updated tesla-preview for Model 3 performance, 20" wheels, new views and color • r/teslamotors The GIF above is low res, but if you use the fan-made configurator above, you can also see with more detail that the new "Performance Brakes" clearly at minimum have larger rotors along with the (same?) calipers in red. I speculate they're 355mm rotors (13.98") as opposed to the current 320mm (12.6") on the non-P models. This is the same size as the Model S rotors and also lines up with the old Model 3 users manual from a few months ago that had the "plus" brake package listed before it was later removed: Furthermore, you can see the "teeth" along the innder diameter of the rotor which are undoubtedly intake vanes for the vented rotors to aid in heat dissipation (a good sign!).
