How are people finding the ride quality? I'm on 18" aero and the ride is really not as comfortable as I would like.
I don't think I would even mind if it was just quite firm, but I find the car just jitters nearly the whole time I am driving it. It is also made worse that often a bump on one rear wheel doesn't just get absorbed but seems to cause some lateral rocking of the whole car.
That doesn't sound right. Maybe get someone who is familiar with Model 3 to test. It would be against all expectations for 20" wheels to make the ride more compliant ... you even less sidewall flex so I can't imagine that's the answer. My SR+ feels glorious even with tyre pressures a little above recommended.
