I'm looking at the Porsche website and it says that the new GT4 does 0-60 in 4.2 sec, while the GTS with PDK does 4.3 (the manual GTS says 4.6). So, is the GT4 really only 0.1 secs faster? It is not as if the GTS handles poorly (it's amazing), and you can buy carbon brakes if you want on both, so does it really just come down to whether you like rowing your own gears and the big wing (which does look very cool)? I just bought a GTS a few months ago, and love it, but am debating whether to take the loss and get the GT4. Note also I don't live in Germany so don't do the "Ring" every day. The reason I went ahead and got the GTS was that I thought the GT4 was going to be a lot more expensive (and faster).
