Is the only differences between the 08 G35xS and the 09 G37xS the engine and transmission? I havent been able to check them out personally cuz im currently in Iraq...

 

...and side mirrors and wheels and curb weight

 

heat seat buttons?

 

Yes.

Engine.
Transmission.
Seat heater switches were changed to muti-position *****.
Wheels and brakes with the sport package, and the springs are slightly stiffer (which means the shocks are probably valved slightly different).
The side view mirrors are slightly different - more aerodynamic.

 

Thanks... So any decent coilovers out for it yet?
