yes, but proper seats are part of having a performance car. Just the same as having performance tires, the seats are an important part of the package. The only connection between you and the car come from the seat, steering wheel, and pedals. The seat is the biggest factor in being able to read what the car is doing under you.
Something I noticed with the Recaro seats on my 8-state, 5-day non-stop driving adventure, is that I was less tired and had way less aches in my legs and back. I took my 2011 Fiesta on a 6-hour road trip this spring, and as usual, my right knee and lower back was sore when we got to our destination. The reason for my knee is that there isn't enough side bolstering to keep it from falling towards the center of the car. I am contstantly keeping pressure on my knee to hold it in place. With the Recaro seats, the bolsters held my leg in place, which kept pressure off of my knee. I have autocrossed, been on a few different road courses, drive the car daily, and took it on a long road trip. The seats were great in all of those conditions. If anything, I could have used the seats to be more narrow and a harness to really help hold me in when on the track.
Yes, the cost is expensive, but well worth it. The entire Recaro package costs less than the driver's seat in my Mustang, so I would say it is a good deal. Plus, it is more comfortable.
