After installing the 20" wheels I have no plan to change the suspension. The PP comes with a GT suspension and I'm good with it. Body roll in minimal, nose dive I can live with, the tire gap with the 20's I can live with. So for all intensive purposes I'm done.
Thanks man, I still have to put the wheels and new hood on. Been stuck in Mexico since November, looking like I might be able to finally come home and get this done some time next month. I have a somewhat complete list of mods in my garage. Once I get everything I got sitting in boxes installed I will do something with the suspension, not sure what just yet. want to get the wheels on first, 315's going on the rear they are wide as hell, can't wait.
Car looks GREAT! Don't see many with Performance PKG; mostly base or appearance. My '14 with performance PKG is currently in production and will be ready for pickup in late June. Can't wait to get it. I would like to see a list of mods. Also, have you done any suspension changes, or have you just stayed with the setup that comes on it? Have you compared the handling and ride to the base model?
