I think 14" will look wrong, 15" are marginal, 16" would be better but you would have to fit lower profile tyres to stop them from catching.
I personally think 15" with a 65 profile tyre is the best. compromise
I came across them a couple of years ago, they would ship to the UK but shipping was 1000usd and then you had import duty and VAT.
The biggest problem is that they have a reverse offset, this means that all the rim is to the outside. You would have to cut the wing and fit 1970's style rally bubble arches, probably not a good look.
