I used a Sparco Sprint last year. Shitty part is it's bottom mount seat and I didn't like the way it held my legs. Moved to a no name brand and I'll post pics of that later.
Me in the driver's seat, I can't see my headlight covers anymore (the passenger seat is a different brand and sits way higher for reference).
I fabbed the mounts, the bottom of the seat is on the floor of the car.
I'm 6'2" 210lbs and more torso than legs. My friend's (5' 10") will sit in it and you'll only see half of their head with the door shut.
