Both my Mach and Focus are lowered (eibachs). The Focus does have a nice "go kart" type feel, but there is nothing like walking the rear end into/through a corner using the throttle. I think my Focus responds a little quicker initially, but I gotta give the edge to the (at least mine) Mustang. Of course the mach is more or less set up for drags from the factory, but RWD and TONS of torque seem to have the edge. Probably pretty close on a VERY tight course, but if there is any straight at all........it'll be the Stang....going, going....gone.
