HEY GRUMPYVETTE?
will swapping from lets say 15" or 16" rims to lets say 17"-20" rims on my car have any effect other than LOOKS?

good question

larger diam. wheels tend to give you the following advantages
(within reasonable limits)

room for larger brakes

faster heat dissipation from the brakes as the rims tend to act as a heat sink, and radiator

less tire sidewall flex

lighter total tire/rim weight

more effective brake cooling

more road to tire contact area

more consistant braking, (see above)

slower tire wear due to the slower rotation per distance traveled

the larger contact area, and less sidewall flex allows more aggressive driving

slightly more pavement to frame/oil pan clearance
