im looking for a 2 seat chassis to build off of. i have an Ultra4 car now (SXOR) but it is a single seater. i am thinking about stripping down my stuff and putting it on a new chassis (347 Stroker, c6 Trans, Atlas, 60/spyder 9, etc). any recommendations on a good starter chassis? anyone bought on they changed their mind on and want to get rid of?
