Reply to "lowered floor pan owners opinions please"

FWIW, dropped floorpans do not reduce ground clearance. A look under the car shows the central spine area hangs below the stock floors by about 2-1/2". So you could conceivably drop the seat pan to that level while still maintaining 'stock' ground clearance. The back of the seat pan is typically lower that the front, and with carpeting & padding removed from under the seat, another inch is also available. It's true that if you simply hack a hole in the floor, there's a stiffening rib across the front that will be cut away and somewhat weaken the floor. But most simply cut the back and two sides of the seat floor, and bend the flap down just behind the stiffening rib, filling in the resulting triangular openings with extra sheet metal. This works fine; I've driven track cars with lowered floorpans that had adequate chassis stiffness to compete. 6'8" is about the 99+ percentile that will fit a Pantera, though....
