I know it's bit late now but saw this posted on Outerlimits regarding the new CCDA (aussie) rules for their trophy class (which I suppose is an equivalent of what I presume is trying to be achieved with a clubmans class).
Specs for NEW Production Class include:
No Turbo or Super Charged Petrol
No Intercooled Diesel
Engine must be of same make & model as vehicle (eg no 4.5 or 4.8 in GQ)\
Can run aftermarket engine mgt system
No 24v winch
Single Shocks
Body must retain origional shape (no ute conversions)
Origional wheelbase to be retained
35.5" x 13.5" max tyre size (must fit through gauge 901mm x 343mm)
No replacement guards or bonnet
Must run synthetic rope
Can run laminated diff & upgraded CV & Axels

http://www.outerlimits4x4.com/phpBB2/vi ... sc&start=0It was also mentioned that a 4 point cage would required for the Vic Winch event (their entry level comp) and a 6 point cage required for the Outback challenge, Cliffhanger, Alpine challenge and all the rounds of the Engel series.
Their rules seem like a good balance, allowing for someone with a fairly standard truck with 35's (which is pretty much the standard these days) to have a go, but not sacrificing any of the safety requirements (roll cage, harnesses, helmets, synthetic rope).
Anyway, that was just an FYI post. I'm looking forward to see what you guys down south came up with when your rules are released. Good on you guys for getting together to grow the sport - the future just keeps looking brighter for Winch Challenge in NZ.
