I'd argue that adding width to the wheel is more effective than diameter. It was noted the the Lambo has 18s, and I think 18 is right around the best tradeoff. Think about it, if the biggest wheel possible equaled better performance, then why don't you see real race cars with massive wheels? Also, efficiency, when it comes to rolling resistance, translates not only to mpg, but more importantly in this discussion to real speed and acceleration. With lower rolling resistance, the engine doesn't have to work as hard to turn the wheel, thus more speed per unit of engine output. However, the tradeoff is grip, so you have to balance grip with low rolling resistance. The point of my post is that optimal performance is about finding the correct balance, which is never done by going to the extreme, such as adding massive wheels. Also, concerning ride and handling, adding weight with a larger wheel adversely affects the suspension setup. So many people add aftermarket wheels just because they look good without realizing how it impacts the suspension. Once again this involves a balance of grip, bump absorption, stability, and the like. If you add a massive spoiler to the back, chances are most of the time it is just for show, but if you ever go fast enough to gain an advantage from downforce, you've probably just overloaded the rear and unloaded the front tires. Hello understeer. Real performance is about so much more than just bolting on stuff.
Also Diarmadhi, ride and handling are not the same thing, and often work against each other, but not always. In a performance car you sacrifice ride for handling, yet you seem to think that handling has no place in a performance car. The only time it doesn't matter is in a strictly drag car.
