Thought I'd post some layouts I made for myself. They're all pretty rough, I don't know if some of them have been done before.

For Kyoto I made 2 straightforward short courses just connecting up bits of the maps with ramps. Mostly avoiding the oval.

The other ones are a bit more silly. The Fern Bay Rallycross starts at the edge of the map and has some steep ramps to make a loop.

The South City one is just random ramps and walls etc to avoid and try to get through a lap without destroying your suspension / clutch.

Interested to hear any thoughts haha.
