To each according to their needs.
For me, if I changed the wheels from factory 18 inch, I would not go 19 inch, I would go 17 inch for softer ride. For Springs I would most definitely not lower them, I would probably raise them an extra 1-2cm, as my driveway is on a steep angle and where it meets the street most of my friends have scraped parts of their car lower extremities off there. I believe the better brakes would be the only part of that upgrade I would love. Spoilers I don't really like and mostly they just add drag. The pedals I don't really care about as I don't stare at them much.
All these extra additions only have minor benefits without track mode tying them all together, track mode is not just a quick software program thought up by the junior computer whiz in Fremont, it was a collaboration between many people including professional race car drivers, of course the $6000 benefit is not there if you rarely expect to take your model 3 to the track.
