as good as they look on that mustang, 20's never have, and never will look good to me on a mustang, it isn't what they are meant for. You do kill some of the performance on it, and low profile tires just annoy me.
You can get the same look with 18" wheels and lowering it about 2", and get performance (rotational acceleration) and still have some money in your pocket, and it will handle alot better (less body roll).
...Those wheels take the stock-mustangs slim and small rims from a "I'm a skinny mustang" look to a "I'm an aggressive muscle car, wanna race .. bit*h?".
i might be mistaken but i believe that car is on the procharger website...it does not look quite the same as they have added a lot of different body parts but i think the wheels look the same...beverly hills edition wheels or something like that
