I am ordering a 2014 GT Premium with track pack and glass roof. Torn between Grabber Blue with black and blue interior or sterling grey with black interior (leaning towards the grey). I want to address the suspension first with a slight drop and plant the stock power before I start modifying. Looking at the Eibach kit with MM caster plates, FR panhard bar for starters. I'm not into corner carving but enjoy spirited driving in controlled environments. What have you guys used with success and best bang for the buck?
