Decided to use up the V730s, the rear left was chunking and this seemed to be the last session for the set before the grip levels plummeted. Corded the tires this weekend, so got full utilization of 13 track days. RE71RS is next for this set of wheels.
Damping was modified to induce some quicker response on corner entry and to allow the car to point quickly for corner exit. Seems like the gamble to make the car very oversteer-biased paid off for this session. Drift sessions later in the day turned this car into a drift car. Hope to be able to do 1:25s and dip into 1:24 optimal times soon.
Lap Analysis:
- T1: Same excuse as always for braking into T1, fighting with ABS while threshold braking is pretty distracting. Sometimes I think I'd be faster without ABS, as my tires are still locking even with ABS.
- T7: Quite timid on the entry, had a massive slide on exit in the prior lap.
Ambient: ~60F, cloudy and recent rain/drizzle
