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.

Session 2 - 1:49.1760 1:41.1580 1:41.1690 1:39.2920 1:38.7010 1:42.2110
Session 3 - 1:48.4500 1:38.7350 1:40.0760 1:40.1030 1:39.0870 1:39.3330
Session 4 - 1:45.3140 1:40.7000 1:40.1980 1:38.8280 1:39.3290 1:38.9540 1:40.2110

Comparison of my speed graph to the previous personal best lap way back in 2013. It appears that the new track surface has aided in speed gains throughout pretty much every corner. However, there is more to gain through more aggressive driving (after I have compared my best lap video with other Z drivers).
