thank you all for the reply`s
after thinking more about it and looking at pics all evening until my vision blurred (or was it the Bourbon ?!?)
i realized that allowing space for driveshaft/ liveaxle movement would end in odd proportions on something so short and low slung.
on top of that i do have to be
very careful with un-suspended mass in a light little car like this,
so i agree that a narrowed r160 irs is probably the only way to make this work.
cant think of any other irs center that is as small as the r160 (and as readily available)
i could literally sit right on top of the long pinion housing...
with a low torque/high rpm bike engine i`m not worried about the small diameter ring gear
looking at the housing ...
... makes me think that a couple pounds of unneeded casting tabs and flashing could be shaved off,
without compromising much structural strength
maybe a
5-link suspension instead of A-arms could give the rear a "classic" flair
5-link will need
a lot of heim`s, but the advantage would be that there is no welding ... so the links could be (polished) aluminum tubing ,
what would go well with my OCARD
(obsessive compulsive aluminum & rivet disorder
)
found a couple more pics... this is a 2 seat Special :
love the bare aluminum body (thats the look i want),
but to me the "fat belly" 2 seaters just do not look as sexy as a slender single seater
maybe with fat tires it would look better....
as i mentioned before this will only be a vintage "
inspired" car;
i dont intend to use wire wheels and narrow bias tires
