Further transformed after a professional setup today.

Used a firm in Colchester that specialise in track hardware - mostly drifting.

The biggest change is in tyre pressure up to 28 front 30 rear from 22 all round. Castor wound back to 4 degrees, 1.5 deg camber on front, .7 on rear, and parallel toe rear and 2 deg toe out front.

Was a bit mystified until I drove it and found it delightful (not a delightful handful). We will have to see. The overall comment was nothing much is going to remove the twitchiness until I source different tyres as the super soft TB15's will always tramline due to their stickiness......

So I gave him the task of finding a set of matching tyres (there aren't any other than the Pirelli equivalents are there??)....
