the lower the drop, the bigger the wheels look. when i first put on my current set, i was dropped 2" all around and in the rear (which was lower obviously) the rims looked an inch bigger. now i lowered the front 4" and the rear 2" and now the fronts look like 20' whereas the rears still just look like 19s. as far as performance, he is right you will get better performance with the lower car in addition to the looks, th elower you go the better your performance. when i slammed the front, whew, what a difference, the car doesnt budge in corners. i am about to lower the rear too though, to four inches as well
