Like Screach I'm also there on the 23rd but will be in an Evo8 and not the E30!!
It's just had an S50 conversion done and if funds allow AND I get it cornerweighted, sumpguard fitted and geo done in time I may well be up for returning on the 15th!!!
I can't recommend Track Days at the Ring highly enough. The past two I've done there's hardly been any traffic at all. In fact I managed five laps without seeing another vehicle the time before last!!
