Scrivy, I posted this in another thread, but in regards to size, you may find it useful...
I'm 6'6" and, sad to say, 280#. Size 15 shoe.
I'm a first time builder and chose FFR for a lot of reasons I won't get into here. But one of them is customization. You didn't say if building was an option but by doing some basic mods to a standard build I've gained ~4" of legroom. The first is a simple way to gain ~2" and, I would assume, could be done on any car. I have a Kirkey lowback seat mounted to the floor all the way back. The seat is made out of aluminum and is therefor very thin. For the add'l ~2" I bolted in a vendors adjustable Wilwood pedals and adjusted them all the way forward. Other comfort mods: I trimmed the brake pedal, got aftermarket driver's footbox aluminum and bent my throttle. I'm go-carting it now in tennis shoes, which is better than I had hoped for at the beginning of the build. I have some Simpson driving shoes and there is plenty of room with those on. I'm doing some add'l clutch foot mods as well; re-doing the footbox crash bar, which really doesn't work for us Sasquatch. Lastly, I'm also adding a dead-pedal.
BTW if you plan to buy something turn-key instead of building, you could always have a pro build it for you with those mods.
HTH,
PS my car has IRS with a torsen rear end, Trigo wheels, a new fuel injected BOSS 302 and Wilwood brakes, yada yada. Right up your alley and can be built by you for 50K... or, with the prices the way they are right now, could probably be found for less used.
