My car looks almost as good as your
I have an 09 S Black on black with Carman R exhaust which makes a little more racket then stock. I have a very mild Cobb tune and IPD Plenum pushing maybe 330-335hp if that much? The Cobb tune changed the shift point on the PDK making feel like it has another 50-60 hp and a bit faster revving. I think your car is the first year they updated the pdk so it shifts a bit faster. It has a little over 100,000 miles on it already so shocks were replaced at 80,000 with Ohlins. It changed the way the car drives. Really tighten things up a lot. I have it set at the softest setting with custom springs that are 100 lbs less then Ohlin's street / track. Caymans are a blast to drive. Your car looks great there.
