any answer to this question guys?

 

J Nez, I read somewhere that it does add to the seat height. Thats
why I havnet been too interested in them. I have found that if I stay
back in the wider part, its not too bad... but since the seat if built for
the track, you can too easily slide forward onto the narrow part.
I'm going to (one of these days) take off my reupholstered seat
material and slightly build up the front part with 1/2" closed cell
"ethafoam", fair it down and hopefully the same material will go
right back.
