One thing to consider is whether you want a pimped out ride, or a performance ride. 20" wheels willbe heavier and have a higher moment of inertia, decreasing your acceleration. It will also increase your overall unsprung weight and the extremely short sidewalls have so little compliance that on big bumps, the sidewall can't compress enough and when the tire comes off of the bump, you get a momentary reduction in traction. This causes you car to feel unsettled on midcorner bumps, causing you to run wide in corners and increase lap times.
