DKing,
Your observations are spot on. The SPF fenders are extended down further and wrap closer to the tire in more of a circular fashion from 8:00 to 4:00. The ERA, Kirkham/Shelby, Unique leave the tire more exposed - all in different ways too. The fender/flare shapes and the lip of the fenders are different when comparing them all side-by-side. The ERA site makes reference to street flares vs. SC flares, which are quite different on ERAs alone. To me, part of what makes it fun and interesting is the fact these cars are all a little different out there in their own suttle ways...

Wait to you start comparing overall shape, body curves, side-pipe mounting height, road height, ground clearance, cowl and rear deck height, etc between all these cars. Decisions, Decisions, Good Luck.
