Looks good and sounds great, but there's far too much grip regardless of tire. The suspension is now top-notch race stuff with virtually no body roll. The turbo had uprated suspension, and I admit it's been years since I've driven a Uno, but this is very far from stock. Acceleration seems to be on the right ball park though. Hope you keep working on it!
The ST2s are the ones that have less grip, even less than the STs.
if you want to edit the "tyres.ini" file, change the values of the ST2 tire like this:
look for the following line on the front tire:
DX_REF=1.40
and change the values like this:
DX_REF=1.30
and the line on the rear tire:
DX_REF=1.385
and change the values like this:
DX_REF=1.285
if that's not enough for you, keep in mind that the lower you go with the value, the less grip you will have
