I am in the market for rims within the next few months and had a question regarding fitment. The wheels I am looking for are offered in 18" and 20" for the 5x105 bolt pattern. To me, 18" might be too small and 20" too big and we are limited on 19" choices. The company does offer 19" wheels in the style I want, however not for our bolt pattern. My question is this, how do these adapters work and what is the cost associated with it. Is drilling a cheaper option?
