OK had a big oops moment and managed to delete several weeks of work on the ini files and around 20 skins based on the 2019 mighty Minis and super mighty Minis grid.
It turned out to be a blessing in disguise as it made me realise how wrong I had things in my first versions. So for the last week I've re-made a handful of the skins and worked exclusively on the super mighty variant. Its getting close now I think the handling is a little off, it definitely seems to understeer and 4 wheel drift more than the real thing but I've got a good basis to work from. I need to get myself down to the rolling road to get power curves for both variations, was there yesterday but had too much other stuff to do so hopefully I'll get it done over the weekend.
