Congrats on an AWESOME decision.
Car looks great man, enjoy!!
DO NOT USE GOO GONE. Your car is new enough, just use a hair dryer / low power heat gun if needed, and peel the letters off. Then use like Rain-X bug remover or something low impact to take off any residue. There are a lot of helpful tips out there if you search. I think it looks best with just 'WRX' on there, the rest is all just 'stuff'.
