Thanks for the feedback.
There were a few private karts at CK yesterday. I noticed one thing in particular, almost all the side pods sweep inwards and downwards. This should improve downforce as the underside area is larger, smoother and very close to the ground. I imagine it’s not that much down force, but then it only needs to be a bit more than the competitors.
There was one kart there which looked like the dogs go nads, can’t remember what it was but the pods and spoilers were translucent.
