Yowzers. Could spend all day messing with this thing. Karts are time drainers because little value changes have big consequences.
@MrB00 @safi hellie see if this is any better. A little easier to get around. Will still lift the front tyre though if you over drive it once the tyres get warm. I don't know what that's about. If I get it to stop doing that then other areas suffer. Just like changing the tyre properties. Add more slippery tyres and the steering needs to be adjusted so you don't immediately kick out the rear end.
The rabbit hole. More can be done but not tonight.
