I had tints done, changed rims to 20" with 275 40 20 tires ( more grippy/comfier than the 21s it came with), cosmetic carbon bits on the side mirror, side camera covers, going to put a lip on it, and want to put a diffuser/side skirts for aesthetics. Probably best performance related upgrade would be lighter rims/tires. I DIY'd ceramic coating on the car, made it shinier easier to keep cleanThat looks awesome. I just got my model Y in white. What upgrades have you made. Looks so shiny
