Being 6'2" I will take a reclinable over anything. Not only that, but the Sparco styling and quality are pretty sharp (to my eyes).
If the car only ever sees one driver, get the light ones. If you are going to demo it with drivers/passengers, I am sure both the drivers and passengers would appreciate some adjustability in your insane (and insanely beautiful) car. Lasty, with that much power, why are you worried about the weight of two seats? Tell your drivers to go on a diet instead.
