| [ http://www.modified.com/tech/modp-0906-performance-wheel-test/viewall.html ] If you can't measure the negative impact of +3.4 pounds per corner unsprung weight between an ultra light weight wheel like a $4000 Rays CE 30 @ 17.4 pounds and a $1200 FN01 RC at 20.8 on a race track with proper timing equipment, same car, same brand brand new tires, you certainly certainly won't notice 1-2 pounds per wheel on the street. It may even "feel" different, but it doesn't perform significantly better. To clarify my backpack statement:
[ http://hpwizard.com/rotational-inertia.html ] 18 pounds @ 11.799 21 pounds @ 13.766 difference of 1.967 kg per wheel of "equivalent mass" 1.967 x 4 converted to pounds is 17.34596 of "equivalent mass" Actual weight added was 12 pounds. Adding three pounds per corner is, according to a guy who believes in unsprung weight is serious business and has put a lot of thought into the theory is like adding less than 18 pounds of static weight. 18 pounds on a 3500 pound street car is completely irrelevant. NOTE: I am completely excluding boat anchors from my argument. Cheap/19"/etc 30 pound wheels are junk and I don't think anyone buying them cares about performance anyway.

Putting AMS garbage, and $500 ebay wheels on a Z is like dressing a Victorias Secret model in a Walmart dress and Payless shoes. You're embarrassing yourself. |
