at 5-10 in terms of height you should be ok. My buddy is 6-1 and can't pass the broom stick test on my car. He would need the Boxster roll bar extension.

The GT3 Seats can be installed or removed in about an hour tops, Depending on whether you have help it can be done in 30 minutes. So for track events its perfect.

I use themn for daily driving but I'm a small guy, 5-7 170 pounds with a 31 waist.
You need a strong mid section because lifting yourself out of the seat with the high bolster is like doing a tricep dip at the gym everytime you get out. I use the ebrake to brace myself and can jump out in one quick movement. Not ideal if you are a big dude with a bulky mid section. It will get tedious, quickly. The misus who is also 5-7 but weighs 120 absolutely hates getting out of them. I thought about putting the stock seat back in for the passenger and using the spare seat as desk chair. ummmm maybe not.
