It was just a matter of time before I will find myself at a wet track day and it is as scary as I imagined! And it was nice to see the leader board all jumbled up with cars within a smaller than usual margin from each other.
The experience has taught me a thing or 2 about driving in the wet. The limits were very low.
A little too much steering angle on corner entry, understeer.
A little too much throttle on corner exit, oversteer.
A little too much braking pressure, ABS! And that probably saved me going into the gravel trap more than once.
Rain aside, the other thing I was looking forward to most about this Winton was testing the newly installed oil cooler. The goal was to record the oil temps whilst on track to see how hot things would get during a session. The rain and cooler than usual ambient temps made this an easy trial for the oil cooler.
And as always a Huge thanks to Nugget Nationals for the running the event and for the photos.
Track driving in wet conditions is a good way to practice focusing!
Session video with data overlay. The GPS and speed data was collected via RaceChrono (QStar GPS), and the temp data was collected separately via Torque (OBDLink MX), so I had to splice the data together to get this. Forgot to look into extracting my Fitbit HR for heart rate data.... Next time! 😆

This was a typical EXE/NN session which means it was run flawlessly and I got a healthy 10+ minutes on track. Shame it was raining which brought the ambient temps down making conditions easy for the oil cooler.

Despite the rain, I was driving as hard as I dared for the duration of the session keeping the RPM up and in the power (or lack of ha ha...) zone, and it didn't even come close to the high 120℃ I was seeing previously! Overall very happy with the findings.

Other bits of data I logged out of curiosity. Coolants temps are well within check and intake temps were nice and low from the weather.
Wet lap PB video with RaceChrono native temp and throttle overlay!
Track wasn't too bad after the rain cleared up, but I was too weak to try for a proper PB by then.
Aways looking surprisingly flat for stock suspension to me. WTB low & racing wheels.
Pre-Some slightly-used camber bolts that got installed pre-track. Time for some negative camber! Fitted and aligned by Ray @ Raceline. A+ service, super friendly, car drives straight, will go back again 😆

The camber bolts gave me -1° camber in the fronts. Without them I had just under half-a-degree, so even though it didn't provide much camber, it's double what I had. Unfortunately all my focus on driving the car in the rain at a much lower pace meant I really couldn't tell how much of a difference these made on track. Next time!
