Nice mods to your 3.0si. I have the same mods on my 3.0si including the Michelin Latitude 's! I decided to add the flares on mine. (Personal Choice)

I am still undecided on the aero kit. My vision is to add the front piece of the aero kit and the rear M Sport bumper with painted moldings and flares. After that, I will add a aftermarket exhust. I am looking at Hartge but will wait to see the results from the Bastuck system.
