I am not big into setups and not particularly great with small details but here is what I have for this kart and track.
270 wheel rotation 18 degrees lock
92% brakes
50 fov
shortest gearing
16 laps fuel
15.7 psi front tires
rear stock psi
I normally just do the fuel and gearing, but I did feel like I got a little more front end grip with lowering the front tire pressure. I only tried 15.7 though, and did not try anything else besides that and stock (16.0 I believe). Based on the rear right tire not getting as much heat or pressure and the rear left I think you could possible increase that tire pressure a little and that may work well, but I wasn't sure and didn't touch it. The temperatures were fairly even across the inside, middle, and outside of that tire though, so maybe its best not to touch it? Anyone here pretty good with reading pressure, heat, and camber for the tires?
