By that measure if you take 3,600 lbs off the car, you'd gain 3.6 sec in the 1/4... but you'd be walking, so something wrong with your logic man
. So yes, it's a lot more complicated to calculate than that.
The effect of unsprung weight, however, sounds about right, with weight shaved on the outside (tires, for instance), making the biggest difference. I just can't understand why people plunk thousands of dollars for heavier wheels than stock... on a performance car
. And not only performance and braking is affected, but fuel economy, ride, and often not noted, wheel bearing life and suspension bushings (depending on offset). But to each his own, I guess.
