Brendon,
Mark's best time was a 12.1 I did not go as I thought I had recaps on my new wheels aquired recently but turns out they are not, bugger. I also heard the track was shocking. Very slippery as even Mark was getting lost of traction when he tried to launch hard.
General consensus was it the times were not as good as to be expected, though Arnie pushed Jonha's R34 into the low 11's. The Croydon mobile got hurt again, possibly head gasket damage or worse. Not sure as again just word of mouth but I will be in touch with them this week.
