Great car, period! But, great can be improved...my observations thus far...
. Slightly larger rear swaybar
. Increase front track width a hair or two
. Stickier tires - the stock fare are horrid especially in the rain
. Stiffen either the front or rear bushing - but not both - in the front lower control arms
. Steel braided brake lines...initial brake travel feels a little lifeless
. At about 15K miles a set of Koni FSD or the adjustable Yellows...but the ride is too good to destroy
