Im looking at some corbeau A4 seats but I want to make sure I will fit with a helmet on. anybody else this tall with aftermarket seats?

 

I got the forza's which are fixed seat similar to the A4's in size/height. I am 5'9", and with my helmet on, i have a 1/2" clearance to the roof Not much room

My seats are on factory power brackets tho, so with a different bracket you could lower it down and maybe gain an inch
