i am also planning on upgrading my suspension next spring.... car is in storage for the winter... and i am looking at the same setup to go through corners on a road course with my daily driver. I will probably go with the 05-10 setup with either Steeda HD Mounts or J&M Camber Plates. I drive a 2012 V6 Pony Package. I have read lot of good things about the Steeda Sports Springs for daily drivers. I have seen a lot of recommendations for Koni STR.T with Steeda Sports, but have not seen many full Steeda suspensions.... i will keep an eye on that thread for sure as i want to know how the Steeda setup behaves on daily duties.
