2wd really? Man you are very brave!! .18cvrx is being watched on ebay at the moment! Gearing would probably be for a dacent top end on NNRC with a pipe to boost acceleration. Tyres kind of depends on when the dates are. Muddy track would mean Dirt Works for me but dry track and I will either have Bow-ties or Lugnuts on. Definitely the ARO towers and buggy shocks but possibly the JT will make an appearance! Futaba S9402s' all round and a newly painted shell plastered with CEN stickers. That set up would be enough to worry any class, I mean you are talking well over 40mph which puts you up with the Truggies in terms of speed! Wealest link as always, is the driver.
WALES?!! I can see the Welsh mountains from my doorstep but that is about as close as I normally get! The South of England has a wealth of tracks. J28 is so called as it is just off junction 28 of the M1 and the Maxbashing track is probably the best in the country. EMORC is the Essex track and is astro turf with a huge tabletop jump. These are just guesses though, I might be way off. I will see if there is a short list of candidates.
