I haven't spent much time in the PC2 kart because it doesn't feel right out of the box. That's not to say it cannot be tuned better, but the general reactiveness of the steering is wonky. The overall steering amount in stock form is actually pretty close to realistic, albeit a touch too much probably. I did dabble with it enough to see that it's a little more than 180*. I play Kart Racing Pro on PC and it is far more life-like and set to 180*. That's the minimum and it steers like a real race kart that way. In stock form the steering feel in PC2 is exaggerated as to what one should expect in a real racing kart. Real karts are indeed quite sensitive at speed and the turning ability comes on quick as you increase input due to the way the steering/chassis geometry works. The problem with PC2 is that it's just too much of everything. It feels too direct and when the turning ability really comes on, it comes on way too fast. There should be some predictability in the way it happens and in a sim that has a lot to do with the FFB. What it SHOULD feel like is this... initially there is quite a bit of resistance at speed. As you gradually increase input for turn-in it should continue to feel resistant. Once the steering and the loading gets to the point where the chassis begins to work properly, this is where the magic happens. This is when the kart REALLY starts to turn, but also the steering should get lighter, but not completely numb. It's been a while since I tried the kart in PC2, but my gut tells me the problem lies mostly in the FFB. The reactivity of the FFB is too car-like, just with minimal input.
More kart blah blah blah: Karts run quite a bit of caster. So when you steer you're really trying to turn the tire INTO the ground. That's why they feel so heavy. This is intentional because this "jacking" is what causes the inside rear tire to lift off the racing surface. This is how karts are supposed to work and this why the turning "comes on" so abruptly. As mentioned above, without a differential this is what makes a kart handle well. It must 3-wheel. So when you steer, you're literally lifting the chassis off the ground and losing all contact of one tire. This is why race karts are so sensitive. Also consider that a race kart has a much more upright steering wheel rake. I'm guessing most sim wheels are set or come with a mount that puts the steering wheel at about a 20* rake angle like my Fanatec. A kart is more like 55*. The steering action of the driver is much more in/out rather than up/down. Most drivers hold the wheel at 8 & 4 o'clock palms up rather than 10/2 or 9/3 in a car. This puts your forearms almost parallel and your upper arms and elbow almost against the drivers chest/abdomen. This "bracing" is how a driver achieves better control of a vehicle with such sensitive steering.
Hope I didn't bore you but there are major differences in karts versus cars. Even in PC2, it's not necessarily "wrong" per se, but it does need some refinement to be both more accurate and enjoyable.
