Ariel Atom Club organised trackday on the Pembrey Track, was wet in the morning, dried up for most of the day and then torrential rain finished the day off.

This is my quickest lap of the morning, track still damp in places, with a passenger and ZZS all round, with the tyres now 7 or 8 trackdays old, rears on the wear markers, slightly more life in the front tyres, according to racebox mini, pulling 1.42G in corners, a braver driver with newer tyres would be pulling much higher.

The fastest cars were hitting 136 mph down the straight and a good 6 seconds quicker.

No problems with noise trackside with the normal exhaust, also no overhating issues for a change.

Laps timed via racebox mini and racbox app on IOS, GoPro Hero 8 Black, guages added via dashware.

GoPro hardware is great, GoPro software is awful.
