The problem with Sparco is that they are fixed. If you aren't happy with the angle tough titties.
That said I would swap in an instant for the graduated Mazdaspeed. I love the seat covering and there is more side bolster.

With the sparco, I find that it is perhaps a little too hard for long distance driving because of the lack of cushioning in the seat. Also, being a midget, I have to push the seat quite bit forward to reach the pedals comfortably, which then cramps the room for flailing my arms about...

That said, I would find it very hard to go back to my standard seat, as it had absolutely no lateral support at all. Switching to the sparco added 30hp to the seat-pants-dyno. It's that much better.
For longer drives, i just put a (discreet black) towel folded up 30cm^2, which does well to get me over the steering wheel

and softens the bumps for me..
If only I could find somewhere I could get some high-density foam / seat back-cushion thingo that just lifts me 1" from the base and the back...

At the mo, the left wing of the sparco digs into my shoulder unless i drive ummm... spiritedly..
