I haven't really noticed a difference between my 17/18s versus my 15/16. I do believe there is a difference, its just pure logic. But I'm not a hardcore racer so maybe thats why. One thing that no one mentioned is that the added width will help cornering and overall handling. While you may give up a little in straight line acceleration you will pick up in lateral acceleration, right?
Another thing that I'm going to mention, is that when I got my 20 X 10s they weren't heavy at all. They are billet aluminum and 2 piece design, but overall they were quite light. Maybe 18 lbs, which I think its light for such a large rim. It was the tire that made them heavy, run flats are not light by any means.
Mao,
Your running TE-37s right? Those are considered some of the lightest wheels, how do they compare to your stocks? Just curious.
