got all of you beat i am 6,2 and 260lbs. i have mastercraft rubi's in my jeep for about three years now and they are still working great. the bolstering is enough to keep you in but not enought that it is a pain. i would not go back to anything else at this point. i have a hard as a rock yj and i have had reconstructive surgeory (back and hip) so i needed something comfrtable but good for trails too. i actually shifted my driver seat inward for more space away from my doors.
coinsidentaly, i have a wrx too and the momos that are in it are not that comfortable. the bolstering is a little too high for daily driving and they are kinda hard. i would go with masters or corbeau if it was me. you will never waste money on a good seat. you would be amazed at the differance. and if you can't see spending the money then pick something about three hours away and drive there and back and you will spend the money easy.
i don't like the newer tj seats because they are too soft. when you get in them they sink in like two inches and i don't care for it.
