I was curious how you can tell the difference between 2005-2006 OEM Stock 19's. Im planning on buying 2006 19's but how do i know im not buying 2005's. Well thats my question, hope theres an easy simple answer! Also If Im throwing on 06's 19's on my 2003, do you think ill need a drop, if so, whats good springs/suspention kit to suit this? Who wants to be a hero? get back to me fellow g men!
