Gimp has a really slow kart now that there are different kart parameters.
It was always my favorite kart but now I'll probably have to ditch it, because it's way too slow.
My best time on Cocoa Temple is around 2:40 as Gimp (all blows allowed, 3 AI karts) which isn't enough to win on the hardest difficulty,
but I can do 2:25 with Xue quite easily. Isn't that sad?
But I guess it adds another level of difficulty: Okay, you can beat them as Xue, but show them the Gimp you got now!

So IMO once there's an online high-score board, it should keep separate records for different carts.

If you are having a hard time, you can always edit his kart file and make him heavy/medium/light if you want.

We are still experimenting with different karts physics, maybe you could create a ticket where you explain the problem? It's very likely we will need to further tweak karts physics based on this kind of feedback
