Don't enter turn 1 too high, aim to arc into through turns 1 and 2 fairly late and keeping the car quite pinched through the exit. The car will push quite dramatically on the exit of turn 2 and reducing the scrub will dramatically help tyre wear and speed. Turns 3 and 4 should be easy flat throughout a run with fairly excess grip. Caution at the end of a stint on the exit of turn 4, depending on weather. Do not go under the white line in 3/4 at any point - any contact with the apron will cause an instantaneous spin.
Expect to lift into turns 1/2 after 20 or so laps into a run. The set at default conditions (78F track temp) will be slightly loose in clean air, but you will either need to go slightly negative (around -3) or more positive (up to +3) if the car gets loose (negative) or tight (positive). If track is colder than 78F, go 1 click higher in 5th gear to compensate for the higher speeds.
