Without seeming to be kicking a dead horse here, and i now realise that the intl ed comes with extra susp parts and both chassis plates... but as far as the actual kit is concerned, is there two versions of the Photon kit? rubber vs foam? and if so can anyone help me out and actually let me know the differences. Are all the molded peices of the same hardness??? is it just a different chassis and top deck??? differentials different??? no spool or one-way???
