I am 6.4 and realized that without seat I can fit in any Cobra. Which made me use kart seats (or a thinly padded R-Model seat). Most seat upholstery robs a lot of space. As does the seat runner.

However, I am also skinny. If your thighs have body builder dimensions, you may touch the dashboard (or if your tummy has... - there is a 14" steering wheel can be the answer)

Some kits (not ERA) have quite space robbing door hinges. Your knees may rub those.

Look for space next to the clutch pedal (if you are not racing). Stretching that leg helps on long trips. Stretching your right leg results in WOT - which will also shorten the trip ;-)
