Most all of what you posted seems pretty accurate to real-world Aritz! And it seems to apply mostly true to the game as well which is great
I agree with Schwoni that seat position is really important. I like to move mine back one or two clicks to get more rear grip.
For tyre pressure, I've noticed that the lower pressure makes the kart take a while to get up to normal grip levels, as you'd expect. I've been running 9.4 psi lately, which is comparable to the tyres I use in real-life.
aireisor,
A narrow front track will let the kart roll more freely off the corner and scrub less speed off. As with any adjustment in karting, it is a trade-off to find the right balance between your turn-in grip and your speed off the corner. The wider front will help on turn-in, but it also tends to set the inside rear wheel down quicker too, binding the kart on exit more. If you can run a narrow front track without giving up turn-in grip, you can get off the corner better and down the straight faster.
On axles, I haven't really felt much difference in KRP between them. Typically I run medium to hard in real-life, because they allow the rear to pick up quicker (more direct transfer of weight) and give the rear more stability. Axle tuning is really a fine art though as you said Aritz. Axles will do different things under different track conditions. A stiff axle may work well on a cold day since you're digging the outside tire into the track harder and you're getting more traction. A stiff axle may also work on a warm day with lots of grip as you are able to get a better transfer of weight and quicker lift. I always start at medium and then adjust according to the track conditions.
I wrote a setup guide for the Merlin kart, maybe I'll post it if you guys are interested in seeing it?
