How much does AC use? Search says 8kW max on Model S. Seems silly to worry about.
Every Watt counts!Worry? Do you want to win the race or not?
I don't have measurements but I test fitted 19's on mine yesterday and they fit just fine. The 18" Aeros fit on the front but their inner barrel diameter is just a few mm too small to fit over the rears, so I'd imagine most all 19" wheels would fit.
Haven't put these on the car for good yet because there's a lip around the base of the center hub bore that prevents my wheels from mating flush to the surface of the hub (see second and third pic). Not sure if this is specific to just the Performance brakes, but I've ordered 5mm spacers with 70.5mm bore, which should be plenty to clear the ~3mm lip.

Does the non-performance upgrade have this lip too? This is really annoying. I might remove my upgrade now.
@FlyNavy01 did you test fit the stock 19’s? Do they have the center bored out as well to accommodate the step? Do the back discs/hub have the same step?
Watched a video that shows the regular front disc/hub without performance upgrade and it doesn’t have the same step.
Looks like in the vid that if the front discs are thinner it would expose that step. Gotta look for a close up pic.
The other question this poses is whether the 20’s have a different offset than the 19’s.
@N54TT The offset of the 20s is 35mm.

You can take it off.Which spacers are you going with? They'll need to clear the 10mm screw that holds the rotor to the hub. Or maybe it can be left off?
Assuming the studs are long enough, do you think a 5mm slip on spacer is an issue?So you have to use a spacer for aftermarket wheels on the Performance Upgrade Package version. That sucks. I hate spacers, I’ve had issues with them in the past.
You just need wheels with a large enough center bore.So you have to use a spacer for aftermarket wheels on the Performance Upgrade Package version. That sucks. I hate spacers, I’ve had issues with them in the past.
I went with these 5mm spacers from Amazon. Only $22 for a set of 4 and they seem to fit just fine (see photo below). I'm still running the 20" wheels without the spacers for another few days, but here's a photo of testing fitting them on the front hubs.Which spacers are you going with?

Nice man. I love this forum and the DIY fixes!I went with these 5mm spacers from Amazon. Only $22 for a set of 4 and they seem to fit just fine (see photo below). I'm still running the 20" wheels without the spacers for another few days, but here's a photo of testing fitting them on the front hubs.
5mm is small enough that it shouldn't create any issues while still clearing that small lip. I'll be leaving the hub bolt on since my aftermarket wheels have back-pad pocketing just like the stock wheels, but you should be able to leave it off without issue.

You just need wheels with a large enough center bore.
Hub centric rings aren't strictly necessary, the lug nuts are what center the wheel.
Doesn’t that mean it’s not sitting flush? No vibrations?I'm still running the 20" wheels without the spacers for another few days, but here's a photo of testing fitting them on the front hubs.

The stock 20's appear to have a small ring machined around the inner bore of the wheel to account for the lip. I wouldn't drive on any wheels that weren't flush mounted against the wheel hub, so I hope others are aware of this issue before mounting aftermarket wheels to their own Performance Upgrade packages.Doesn’t that mean it’s not sitting flush?
