if you want it to fill the wheel well then lower your car. it not only helps out in performace it will also make your wheels fill the well alot better. the ride will be better with 18s then 19s

 

go 20'ssssssssssssssssssssssssssssssssss that would be sick as all hell!! iam in the same boat! if i wanted speed i would have bought a s4 or a evo!!! But i bought the car for looks and to see what audi has to offer! i also was thinking on putting 20's or 19's becausei have not seen anyone with 20 but i dont know how they would look or how much work would be invovled to make them work! but if you do it i wanna see pics if it looks sick or if its a little to much rim

 

the reason no one has 20's is cuz they wont fit lol
