It sounds really stupid but I know he took the seat out and bent the bars down laterally, i think he removed the seat lining to do this but I'm not 100%; after that he put some additional padding in the center portion so i wasn't sitting so deep in the seat; i told him i didn't like it because i felt like i was sitting too high so we removed it, as it is now those bars are literally bent outwards but not too much to deform the look of the seat or anything that is noticeable, but just a few inches made all the difference to my legs. I spent some time finding the right shop, I would think it has to be a shop that does interior high end custom work, you could call Porsche and ask them where they send their cars for interior work or repairs? Thats how I found my shop.
