Hehe Chris, I didn't look under too many of the bonnets at the end of the day, but I suspect they would have been pretty mucky.
Yeah the boys were having a blast, no breakages this year. If it had been on the grass I would have gone for a zoom around, but when we got there to be greeted by the dirt with small rocks in it, no way. Got enough dirt and stones caught in the control arms and coilovers as it was just driving 20 metres to where I parked. Went straight down to get them blown out yesterday morning.
