The old version of Ballarat is in Kart Racing Pro! A massive thanks to haune90 who created this for rFactor 2 and allowed me to put it on KRP.
I realise it's a bit buggy like tyre walls are see through and all that but I will fix it in future versions. As of now I'm working on the new version of Ballarat
