According to my 928 brochure, main differences with GT are:
Manual
Sports seats
Sports suspension
20kg lighter
'Sportier' torque curve and gearing
10 bhp more
And I believe it was about £15000 more expensive!

GT: revs at 3200 rpm at 80 mph due to 2.73 rear end
S4: revs at 2400rpm at 80 mph due to 2.20 rear end.
That's the biggest difference you would notice from the driver's seat. If you cruise at 85 mph the GT will feel like you need another gear and the S4 won't.

But you're right Ryan - why we are tripping over ourselves doing smyth's research for him is a mystery.
I don't post about wheels. I just don't care, really. They could look like this, they could look like that, but they are all shiny. Big whoop.
