I heard that when you change your wheels after modding at a transfender (or that other modding place in SF if it's an elegy, jester, uranus, etc), it changes the handling of the car somewhat. I tried to look this up on the net but had no luck. Is this true, and if so, what affect do each wheels have, is the performance increase relative to the price of the wheel? Also, for other mods such as rear spoiler and vents, do they have any effect in terms of things such as performance, weight and handling?
