I am asking on this board becuase I know you guys mod your cars way more that anyone else, so no flaming please. I have figured out that changing from the stock 16" basketweaves to 20's w/ the right tire size will give me the same rolling diameter, but should I go smaller in an effort to get a little more performance? The 19's will weigh slightly less, I can change tire size to keep the speedometer correct, but would it be more beneficial for me at all? Lastly, will getting lighter weight wheels really ive me anymore noticeable power...I thought that there was some equation saying that 1lb at the wheel is like 10 in the car. I love the iForged 20's, but I am trying to justify the price of picking up some 20's package complete with tires for the same 2k that I would spend on just wheels alone.
