Northy, can we have clarification on the term "the same chassis must be used" is this classed as the car or the actual chassis plate or tub.
For example: the cat chassis can be removed with 10 screws and bolted onto another 95% pre-built car, You are still technically using the same chassis.
I would like to avoid this scenario and have to replace parts on the 'car'.
Also how much are we allowed to have pre built, for example, can we have a b4/x6 front end ready to bolt on, and gear boxes made up etc or is it a case of having to replace the individual parts at the time, right down to diff balls if needed.
Hopefully by clarifying these points everyone should be on a level playing field
