You already seem pretty good! But the main tip I can give is to make sure you optimise corners for the most possible exit speed AND try to use the whole width of the track to do that. One other thing I can recommend is watching some karting content with commentary, I've personally been watching PericoKarting and Cameron Das Racing recently, and It's helped me quite a bit. Anyways nice vid! I hope this helps (/≧▽≦)/ PS: I love the moment at 7:58 hahaha
Thanks alot man i'll try to implement that in the future. And i have been watching a couple commentaries but not alot, i will go watch more and i'll do my best to improve :D again thanks alot for the tips and i will really use it.
