Previous time on this layout was 1:19.317 so over 1 second off. Same tyres (however quite a few more laps on them) however spring rate increases to 10/7 (9/6), front OEM sway bar installed, ride height increased 25mm, rake of 5mm added and 2 way diff (same ratio).
Rear brake bias was tweaked and the lockup was reduced, however the high initial bite of the pads takes a bit to get used to so braking a little early than should (time can be made up). Words from those following me was I had a few BIG lockups in the rear, but these were caused by way too much speed into the corner. The 2 way diff takes some getting used to so need more seat time.
With the exception of tyres, more than likely no changes will be made before the next general practice. Only possibility is lowering the car 25mm however this requires changes to the splitter and may not have time to make these.
All up very happy with the day and the baby steps being taken.
Only downer for the weekend now is I have been found on Facebook
