Aftermarket Wheels on Model 3

Ah!
Technically, the center of the front wheels are only spaced ~12mm further out than OEM 20x9+35 (this +40 offset is nullified by the thicker rotor hats, meaning only the 12mm spacers really count). So, the front track width is technically +24mm, and the rear offset (and therefore track width) is technically factory.
That said, an inspector might be skeptical based on the appearance. (I also think an engineer would not ignore this part either…). The outer edges of the front wheels are 37mm further out than stock on each side (+1” on either side of center, plus 12mm =37.4mm). Coincidently, because I added ~50mm to both the wheel width and tire width (9” to 11”, and 235 to 285, the outer edge of the tire also moved out by the same amount.
Just by the math alone, the apparent track width is 3” wider.
Still, there’s more. The extra 2+ degrees of camber also moves each contact patch away from the center of the car by another 25mm on each side. If track width is measured at the actual contact patch, which has been further displaced from centerline through suspension geometry, that makes the total increase in technical track width about 3”, and total increase in apparent track width about 125mm, or 5” (for the front).
Bottom line, there are arguably lots of ways one could measure (or report) the change in track width, depending how far into the weeds one wishes to go…
(Sorry I jumped back and forth between inches and metric so much……. If only there was a way we could just count using our 10 fingers instead of the lengths of random kings’ thumbs and feet…)

I had a coolant leak fixed in the fall (~38k miles) and they didn’t say anything negative. Of course, this doesn’t mean I’m not on some secret blacklist (as much for all the other suspension mods, or even my track mode data, vs just having aftermarket wheels).
My service center replaced my front upper control arms for part cost only and free labor. I had numerous suspension mods including coilovers during the service. They only warned me that they wouldn't be able to get camber within spec which I didn't want them to anyways.
It really comes down to the tech and service advisor if they want to make an issue out of it.
Went to the Unplugged Performance Fremont gathering this morning with a few friends:

Google “Aerodynamic Splitter!”
(Granted, I’m not sure how valuable a splitter would be for real times on a car with bags instead of solid coils & dampers, but I have no judgment of others’ tastes!)

Nothing but compliments so far
What a spec!
I think I would go for the S/T if I had that kind of money rn.
