yeah, it's rad isn't it? i love innovative things. and it looks super quality too. i was thinking of a geared rear and mission style belt linking the two diff pullies. less rotating mass that way and larger diameter pullies to boot.
i was playing with an fsr bullet a while back actually thinking of doing just what was done on that tech car using two sealed gearboxes from 2wd offroad cars with a piercing layshaft to a transfer belt. never enough time...or was it motivation?
