Both of the cars look fantastic...
so the SA-60M have a straight bit right off the rim and then curves into the "spindle" area.
where it seems the SA-55M looks like the style of a RG-II but completely reworked... I like both a lot, but I think if I was buying a set, I would opt for the 60's, but that could be because the straight section of the rim seems to match the rest of the body modifcations that John has done that have a straight/solid line feel to them, instead of the usual curvy, like stock body FD's are....
BTW John... thats mean... Just posting up ONE picture
