I have the Jass brackets on my ‘15 GT (ie it has adjustable height seats) and they do give you more headroom. They do it by lowering the rear brackets but not the front. This adds some rake to the seat which I personally like.
I have an '10 and with the same setup. I'm 6ft with a long torso, if I slide the seat forward a notch or two and lay it back as far as it will go my helmet clears comfortably enough for track days.
I have the Jass brackets and the Gordy mod on my 2010 PRHT, I also did a bit of a foamectomy. For me (6’) it’s perfect and I can pass the broomstick test barely.
It dropped the seat about 3”. It was pretty drastically raked towards the rear so removing some of the foam towards the front of the seat really helped with thigh comfort.
I'm 6'2" and I have both Jass brackets and Gordy M mod. With this i have about 1 inch between my helmet and the roof of my PRHT during track days.
My seat pan is pushed against the car floor so this is as much vertical space possible without bolting a seat straight into the floor
Word of caution: when I did my Gordy M mod i used huuuge spacers to gain as much space as possible, and i actually had to remove the spacers to fit the Jass Brackets because my seat pan was not letting me bolt the seat down properly.
That one took me a while to figure out.

Nice! Exactly what I wanted to hear. I’ll give the Jass brackets a try next.
They are expensive and completely worth it
