I'm 6' and 230 Lbs, and although I don't own a Porsche, I do own 2 BMWs and a Mercedes, so I'm pretty familiar with GOOD German seats. My '06 A3 Sports package seats are short in the cushion and the cushion doesn't tilt enough for my taste. But, I did do an 1100 mile road trip last summer, and never did I feel beat up at the end of the day even with my SR Vogtland/Koni GP Coilovers (the stiff ones). My car was also used as the template for Recaro brackets by Speedware in Redmond, WA. so I know they have the pieces if you want to swap for some Recaros. Personally, I found the Premium Package seats to be way too soft for my taste, so I couldn't recommend going that direction.
