Re: ED sprint wheels ?
I used to dream of a 17" or 18" version, which of course does not exist. Later model AMG Mercedes wheels look very similar (remembering the EA SVO style wheel was used on '80s AMGs, but with AMG written on one of the spokes), which would need custom hubs to fit on a Falcon. Would suit an EF/EL because of the softer lines though.
Anyway, because big wheels have so many millions of disadvantages (weight, bulk, cost, tyre prices, theft likelihood, rolling resistance, performance/economy/ride losses, etc) I think 16" is a great compromise personally.
