Dann, as long as this lead is aerodynamically shaped to increase aerodynamic lift, yes, your GT will not only hit a higher top speed, it will also make you reach top speed sooner since you're going to be increasing traction, and if you place that lead on the front, it will also keep the front tires on the ground. then once you get to around, oooh, 20 mph, the aerodynamic lift will take over and your rolling resistance will decrease.

How do you think the JAto goes 65 mph when it's heavier than your GT or my XXXNT?
