I'm nealy 6'3 but I don't have super long legs or a super long torso both are about equal. My head just clears the softtop with the stock NB seats and my head didn't touch an NA's hardtop when i sat in it. I plan to mount my seats on the floor just because i'm tall enough that if I ever want to beat the broomstick rule I need to get that extra head room for my helmet. Plan was to get the Momo's because they are cheap and FIA certified without a brace bolting them to the back wall like some require. That'll all have to wait till the fall though.

 

I'm needing the lower seat to clear the roll bar even though I'm only 5'8". I have an autopower that sits way back from the seats. Great on a daily driver because there is no way my head would hit it even with stock seats. Sucks on a track car because it sits too low.

 

By the way, I just saw today a very tall guy in a miata with the bride pro seats. It fits great and he says he had no problems with these. These are nice seats, but the bride sliders and expensive.
