Me and a guy called Doug (who hardly comes on here but has a Kuro 350) went along, and had a great day. Works out cheaper than a proper track day, as we only went through half a tank of fuel, instead of a full tank, and its alot easier on brakes, etc too. Doug was down to the wear markers on his rears when we turned up, and we had a good look at them after, and there was no perceptable wear on them at all.
