there's at least a couple more F4R powered mk1's from round my way who aren't on the forums, Wobba is there in the ITB'd and grippered Williams, adi as mentioned in the boost bus with rear turret conversion, bass is standard F7R for track, no boost.
then paddy lah if he makes it on the itb'd beastie in time, Ryan with another standardish Williams powered job.
matt and duane/steph in cup cars
allan and summeh in another Williams (Rax's old one)
dave in his willy 3 (fairly standard I think)
so a good turn out imo
