Here are more spy pics of the 2013 911 GT3 out testing. With its large rear wing, unique front bumper (still in testing phase), and center exhaust it's obvious to see it's different from the standard 911.

Porsche is said to be cutting the overall weight down (around 40kgs) on this new GT3. Power will also increase from the 3.8L to over 450bhp.

It's also rumored that the PDK gearbox will not be available, making for a true drivers car with a six (or seven) speed manual.
