I used to drive company Foci all day and they all have a bar that drive into my lower back plus I like the cushion positioned all the way down, but it leaves a huge uncomfortable gap between the bottom and the seat back. I driven my buddy's Recaro EAP before and it was a night and day difference in comfort. If my buddy didn't sell me his EAP for a steal then I would've bought a replacement Mustang just because of those horrible standard seats.
EAP with 1/3 of the cold weather package. No block heater or TCS.
