He's a helpful chap too. Said he'd pass on any technical pics of the 575 GTC if he came across them in his plentiful archive (bit late now though, but still cool to see). Spotted him at Spa 24 last year too, he was doing some filming stuff so didn't bother him.Just a thought; the guys at Racecar Engineering Magazine love SuperGT - especially Sam Collins, who is the (an?) associate editor IIRC. He does the primary commentary for Nismo TV's live coverage of Super GT as well. They may have lots of information, or at the least contacts who do, which could be of huge benefit for you with that.
