PIARC Sprints - Phillip Island

Rainy day, only managed a 1:53.13 during the dry session in the middle of the day. Still almost two seconds off my PB.

AROCA Sprints - Winton Raceway

I haven't driven the Winton Club (Short) Circuit for more than 7 years, so I was keen to see how different the car and me are now combined with the new track surface.

Session 1 was not timed as it was a practice session and we were driving to around 80% capacity. However RaceChrono showed that I clocked a 1:10.8 which was already 2.5 seconds faster than my previous best time.

In session 2, I was able to start pushing and I finished with a 1:08.5 - 4.8 seconds faster than my previous best.
1:18.4065 1:11.6445 1:11.2580 1:09.1216 1:09.7839 1:08.5055 1:10.7413 1:08.8626 1:12.1030

There was no further improvement in sessions 3 and 4, but I still managed to dip into the 1:08's.1:20.2357 1:10.2046 1:09.5703 1:09.7438 1:10.3324 1:08.9062 1:09.9414 1:13.0515 1:09.6468
1:21.8112 1:11.1080 1:11.4054 1:09.0989 1:10.8316 1:08.7809 1:11.6312 1:10.2478

It's interesting to note that I can still go a fair bit faster through sector 4 of the lap (turns 7, 8 and 9), with RaceChrono showing a theoretical best of 1:07.2.

A speed comparison shows big gains throughout every part of the lap, especially the sweeper at turn 3.
