I just switched mine to a k&k aluminum flat back mine was a box seat and I switched it out to a pan seat.. The pan seat is a little heavyier than the box however.. The pan looks better my .02$ and I needed to move my battery out front for extra weight out there anyway.. The heaviest piece of the pan seat is the piece of channel the seat connects too.. I may make that out of aluminum after I see how much weight I lost this winter off it..
