If you aren't using Parc Ferme rule or you want to set up for the 'race' (sacrificing 2-3 tenths in qualifying but with great benefits in race pace), usually I test setup in practice with medium-high wear (20-30%) and my results are typically:
- add some click in wing, especially the rear (for example Spa 16-12 TT --> 19-18 Race / Silverstone 28-18 TT --> 27-28 Race)
- suspension less stiff (Silverstone 41-15-8-1 --> 30-5-1-1)
- I adjust differential on release if the new wings need it
- tyre pressure modified to be in the range of perfect temperature if needed
Hope it helps to give an idea, but I suggest to make effective comparison tests in track 😉
