customizing my seats
 

So I have this idea, and I need a few opinions. I figured since it seems to be that due to railing issues, aftermarket seats tend to sit higher in the fc. So, my idea is to get my seats re-upholstered and remove a layer or completely change out the cushion to give an extra inch or so. Does this sound like it work, if so, does anyone know of a material that can give the most comfort with the least amount of thickness that i can use to replace the seat cushion with???
