i have worked with luke at classic aero designs to get acceptable headroom and can proclaim headroom happiness!
i am a bit over 6'4" with a 34" inseam for general reference. without any seat cushion or back i had about 2-1/2" of headroom.
my order from cad included an ultra light sportsman seat bottom for the pilot side fabricated with confor foam that maintains great support while minimizing the overall thickness. with the seat bottom my headroom is reduced to about 1-1/4". the standard sportsman seat back that i initially ordered includes a moveable lumbar support, a significant amount of side bolster, and core padding that pushed me forward and up right into the canopy... completely unacceptable.
together with luke and jeremiah from cad we discussed potential solutions to restore adequate headroom. they had me fit 1/2" rigid insulation to the seat back in increments to gauge the impact on headroom and we discovered that there was a dramatic reduction in headroom from the seat back thickness. with just 1/2" added my 1-1/4" of clear is reduced to 5/8"... with an inch it is down to a marginally tolerable 1/4". after discussions the seat back was modified to reduce the overall thickness of the bolsters, eliminate the lumbar support entirely, reduce the core insert to a minimum thickness, and change the foam to confor.
they did an amazing job in making the seatback look great. i was not able to immediately test it though since i had moved on in the build and wiring had overtaken everything.
this past weekend they modifications have proven to be fully functional and my headroom horror has become headroom happiness!
for those concerned about headroom i suggest considering reducing both the seat bottom and seatback and using confor foam. my end result preserves great headroom, more than 5/8" clear, and is actually more comfortable than the 'standard' seat.
here is a shot of the bliss from happy headroom... hard to appreciate this if your hair never brushes the headliner of every car you get in...
both seats for reference... the co-pilot is standard foam and form, the pilot side is with the ultra light bottom with confor and the specially modified thin back with confor.

classic aero designs is the greatest, thanks luke!
