Performance Parts for new 9-3's?

As much time and money I've put into making my SPG look right; I'm thinking it's time to upgrade to something modern.

I do like the new 9-3 Aero that's currently available, but I wonder with it being so new, are there many performance upgrades to be had?

Also, does anyone know any real details about the Aero X that's coming out? Sometimes I read conflicting things when I do searches...

Thanks
