I wanna put new wheels and tires on my b5. Just to give it a more aggresive look and make it stand out. Im deciding between 18 or 19 inch wheels and i want them to fill th wheel well but i dont want it to look like a rice machine. Thanks a bunch

 

This is my car dropped 2.5" on 19s. My sig is the car on 18s.

 

Not quite sure about the size but these guys may give you a good advice.
