I might have this wrong but the adjustments to caster make the front wheels cause roll when the steering is set to turn? The steering isn't on a flat plane?
If that's the case then the caster will lift the inside rear when the kart is going either forwards or backwards.
I don't think the reverse is a glitch though, what happens in karting IRL if you end up facing a wall?
If I'm facing against the wall IRL I'm out of the race. In the game they put reverse in because as someone else pointed out, you can't put corner workers into the game.
There's no easy way to explain it. I've been in karting for 10 years+.
Everything in karting works on a double standard. You move the rear out to loosen then tighten the chassis, as well as moving the rear in to have the same effect. It's actually all very complicated. The entire chassis and driver work together as a giant shock/spring. You just don't hop in a kart to go race if you're serious.
IRL, Weight balance of a KT100 Chassis is 46-43% front weight depending on your chassis type. The drivers height in the seat accompanied by how many seat struts, rear axle bearings, the stiffness of the rear axle, rear track width, and the front caster settings all determine how the rear end reacts to the roll getting into the corners.
The more positive caster (bringing the king pins back) and the higher the driver sits in the seat rolls the chassis more.
The steering transfers weight in the front to the rear. If I turn left, the left front of the chassis raises, and the right rear will load.
Not all classes hike the inside rear up, mainly the faster TAG and shifter 125cc classes. And they don't hike up on faster sweeping corners.
For the record I've spun going 65mph and actually turned through the corner trying to adjust for what I was going to impale at that speed (yes I had that much time.) The front end did not lift in the corner.
I almost shat a kitten when they announced karting was coming to GT. Myself and several other people around me are curious to see how PD did with it.
2-3 days everybody!
