I know some guys are running spacers but didn't have good objective data. Some say 15mm can run without issue while others say studs run into pockets. I contacted the spacer company and couldn't get a clear answer.
So! I got off my butt and just took the measurements myself. These are the 21in ubers. Front and back it seems like the studs are about 27mm in length and pocket depth is just shy of 12mm. This kind of explains why some people have issues with the 15s and some don't. Personally this isn't enough leeway given tesla's tolerances and don't want to shavey studs so I'll probably end up with 18mm spacers.
