oh well, it was worth a try..

we tried fitting some 5-lug sprintstars to the rear of a 356, but they were just way too fat!
it's a real shame as the front end looked good with tucked 4" sprints, but those 'fatty' 6" rears just wouldn't clear the arches (even with relatively narrow 185/70 tyres).
so there you go, if you were thinking (like us!), that a 356 would look cool on sprints, you'll either need a set of skinny rims (and tyres) or some shorter rear axles!
