It's all about the rims when people do this..it isn't about improved performance, or improving the look of the car alone.
That Monte you have pictured isn't bad, I have seen worse, but I don't think that those rims would look good even normal sized.
I don't understand why some people think putting 22s+ on an ugly car, like a first generation Intrepid (a common example), look good. There is NO visually appealing flow that matches the car with rims that big..let alone the rims, despite the size..which is naturally why most people find it to be ugly.
