Same day as the truck racing, the Michelin Clio Cup Series.
Mega wet track day at Castle Combe the other day, good fun though and dried out late afternoon.
Failed the drive-by noise limits though on my first stint out! However when the static was re-tested it was 99dB (100dB static limit), so I was very fortunately allowed back out and to try shifting at 6000rpm (down from my 7700rpm limit) and see if that was enough to keep it in check. Luckily it was so I was able to enjoy the rest of the day albeit with an early rev limit.
Many thanks to BHP Trackdays for the leniency and a great day.
