Waiting to get my windshield replaced on the RS3 then I take delivery of my X3MC. I cannot wait.

I think you're spot on with the tire pressure issue, at least at the track I've run. Here's a close-up image of the track-tire interface from Nov 2019, and you can see how glass smooth it is. I definitely noticed a big difference going from OEM rec psi settings 33F/38R in Nov '19 to 32F/35R in Feb '20.
Next time out I'm planning on 30F/32R and expect, at least at GNV Raceway, traction should be improved once again. After those trials I'll change to race gas to see what gains I get. Incremental changes so I can assess what makes a difference.
