The "Original" Challenger had it's own chassis with a daft mono shock rear end and in board shocks and rockers up front. It was fitted with a Triumph 955i bike motor and tweaked with a laptop to tease some more go out of it. Chassis etc was ALL tig welded which at the time (8ish years ago) was unheard of in Kit Cars.Mono shock did some weirdy stuff when out on track too.....
but heyo if you don't try these things life is boring!
The body will fit the early Ron Champion Locost chassis but will require some dicking about to make it fit.
It will also need to be painted as it never was a gel coat shiney finish.
