Save yourself some money and go gm, 1LE or ZL1 sway bars only $300 with bars and links then buy some take off 2012+ ss springs and top it off with a set of front and rear 1LE struts car will feel great, handle great and look "stock" underneath if a warranty issue ever comes up.
Also we never had a issue with fe4+ style rear sway bar with our v6 brakes you will hear this on the forum all the time that it wont fit but they fit fine.
