Depends on what you want.
For street use-
34 to 36 psi front and rear is fine. If you have higher temperatures in the middle tread then let out some air.
38+ psi if you do commuting and want a little better mpg but harsher ride and more wear on the center tread.
For performance driving you can try slightly higher psi in the fronts just so that the tire doesn't roll over as much but the actual performance and psi will vary with which tire you have (stock vs other performance tire) and your driving style and event surface/layout.
Also, your suspension settings and alignment allow you to use more or less of the tires. Stock suspension and alignment is lacking. Upgraded and lowered suspension with camber kit in front will help make better use of the tires.
Don't run the psi too low- more rolling resistance and you'll wear out the shoulder tread faster which is already the tendency with any front wheel drive car.
