Kart shops use to have this stuff called roll rubber. Just 1/2″ thick heavy foam rubber with peal and stick backing. Can’t seem to find it. Need to fill in some space at the top of the seat.
Does anyone else have this problem, one size seat fits you on the bottom but is too loose on top, next size seat fits good on top but you can’t get down into it. I’m about to start making my own seats. Who are these seats made to fit skinny butt Mr. potato? I really don’t believe any of these kart seats are molded around a real human body.
