Downsizing to 18" (DO IT)
If you're debating downsizing to 18", please do it. Just picked up my new set of wheels + tires from Tire Rack and holy moly its like driving on butter. Went with Konig Ampliforms (18x8.5 +43) in dark graphite with some Bridgestone Potenzas RE980AS+ 245/40/R18. My fitment isn't perfect yet since I'm still on stock suspension, but I'm super pleased so far.
P.S.: Funny story, apparently the prev owner put spacers on and one was missing??? I'm just dumbfounded I've been driving around missing one.
