Ok, heres the deal.....

I lost 3lbs per tire on each corner. I am getting 1.5 mpg more and the car feels stronger coming off a light. I know I am going to hear "You are driving harder", but no.........Exact same conditions. Can 3lbs per corner of unsprung weight really make that much difference?:hide:

12 lbs on a 4000+ car is like throwing a deck chair off the Titanic....youre imagining things.

:dance:Spoke to a good friend of mine who runs BSP and now Street Modified in SCCA and he said 3lbs per corner would make a difference, small but a difference.

So I trust a 10 time SCCA Nationals competitor.:thumbsup:

What he means by "small difference" is "difference you wouldn't be able to notice".

IF you had a precise method of monitoring gas mileage, and an extensive list of track times under varying conditions, you might be able to pick out a half MPG gain on your city mileage, and a tenth better track time average. But you sure as hell aren't going to see anything concrete on the SOTP meter.
