I have an '03 GT that has been lowered 1.5" with Eibach Pro Kit springs. I am contemplating adding a Cervini's Stalker front bumper and side skirts. I currently have 17" wheels w/ 245/45-17 tires, but will be getting 18" wheels with 255/35-18 in front and 275/35-18 out back. Do you think I will be too low to the ground and have too many scraping issues with the bumper and side skirts?
