A tip I was told when I first drove a Porsche (& totally mucked it all up as a novice) was to adjust the seat so that your clutch leg comfortably depressed the clutch all the way in with a bent knee and adjust the seat back to a more vertical position for bent arms steering wheel grasp.
Forget all about other comfort issues - "This is not a car, it's a Porsche! Do ya wanna drive it or sit in ya lounge room?" was sternly yelled at me by the "expert". I obediently complied, took a while to get used to and now I see why.
