The Satuday was foggy/overcast and very wet which suited me fine watching a 4hour race from behind the fence
There was rain overnight so the Sunday morning was very wet and cold (stuff all grip) but within a few hours the track had dried out in the sun and it was 20odd deg - in the end I got in 11laps, 2 were wet (before 830), one with a drying line and the rest completely dry. There were three hour long track closures during the day to clean up big spills and for most of the day various parts were flagged so it was difficult to get a complete clear lap in - despite that I could have easily done twice the laps if not for a km limit on the car (11laps totalled 260km including two trips for fuel) and knackered tyres that I had to spell for 30min+ after each lap (they'd start to go off by the 6-7k mark towards the end of the day). The track was open from 8am till 720pm.
I found pushing on the wet laps was pretty daunting - the golf wanted to swap ends under brakes, but the upside of a wet track is its completely empty while the bikes and guys on r-comps wait for it to clear up. Pushing the golf in the dry was the most fun I've had in a car by a long shot.
btw I take back the cheap part - not even close!
