It's turned out better than expected. The concept was simple shrink the GTA IV Banshee down so it becomes a go-kart. What I didn't realise is that the handling would act differently towards the "car". I always thought that the handling would say the same no matter what the model it was applied to but what I have seen is that modifying the shape of the car changes the outcome of every crash.
Overall it is a change for the better, and its more fun(for me atleast) to drive around Liberty City.
Not bad for a days work.
I will upload it as soon as I have fixed all of the known bugs.
