GSR leather seats are no different in construction than any other OEM 3rd-gen Integra front seat, save for the Integra Type R. :eh:
hbissell, with the seats you have now, you can retract the lumbar cushion by rotating the lever on the side of the seatback.
Another solution would be to retrofit a set of Honda Civic Del Sol seats, but the bottom cushion will be slightly lower (which is counter-productive)
