Hi everyone,
A new version of Tsukuba is out, this is V1.1, it includes new Fastest, Block, Fast_OW1, new pit entry to stop crashes on pit in and new last corner path with a remap of the surface for real road. Go grab it here and enjoy some offline racing at one of my favourite classic Japanese circuits.

There will be a V1.2 of this in the future once I get through some other circuits as I have some corners earmarked for further tweaks.
