Thanks for the pics you so kindly sent me, Jon - much appreciated. It was a good session for me, never having ventured onto a track circuit before (although I did a few sprints and hillclimbs in the way distant past, in a Ginetta G3). Being able to give my Plus 4 some real beans felt great and I benefited from the initial few laps of tuition that were included in the deal, serving to reassure me that I was already doing most of it right!
I might even give it another go if it happens again next year, not least to properly try out the better manifold I am about to have fitted to free up some more horses/torque from the GDI lump. And I'll take my decent cameras to try and get some shots of you, if you are there - to repay the favour.
