Wanting a more supportive seat in my S14, ideas?

[nextproject]

Okay, here's the deal. The S14 is my DD, its not currently built for speed, more for handling (although the wheel/tire/ride height kinda limits that aspect). I am 6'1", 175lbs, so i cannot really indulge in a setup that DECREASES headroom as i was stupid enough to end up with a car that is equipped with the sunroof.

So im looking for a seat/bracket combo that will allow for ALOT more support in the thigh and back/side areas. I'd prefer something lighter than stock with a bit of adjustability (recline) unless the seat just happens to be in the perfect position in non-adjustable form.

I dont ride gangster style with my seatback all the way back.

Im perfectly fine with considering a stock seat from another make (350z, S2000, etc) but im guessing those may actually ADD weight. Which i guess i wouldnt have a problem with so long as its not an obscene amount and the increase in support/comfort is worth the weight penalty.

Just trying to see whats out there and what my options are. The 240 needs a christmas present and as of right now, comfort-wise the seat is my biggest gripe.

I thought about getting S15 seats, but they only seem to be marginally better (at least by just looking at online pics).
