I have a pair of Corbeau fixed back seats that I bought with their sliders to bolt right up to my 986. I originally looked at Recaro but was surprised at how much flex was in the seat I sat in (flexed more at the shoulder than I expected but it could've been the seat I sat in). The Corbeau seats were much cheaper (it was nice to have the direct bolt in sliders) and I found them to be quite good for what I do (autocross). I coupled the seats with a Simpson 6 point harness and bolted the harness directly to the car (no sub-mount).
If I had to do it over again I would've definitely considered a reclining back seat as I don't like to take the seats in and out and could use a little extra comfort. If I were a die hard racer than I would stick with the fixed back seats as they weigh so much less.
