Lighter is faster.
Very basic concept:
Weight does increase traction. Weight does increase centrifugal force. The traction force gain is less that the centrifugal force gain.
This is why Aero plays so much importance in car classes that allow it. Traction goes up without weight going up as quickly.
I could lose a few pounds. The cornering gain would be more significant than the acceleration gain is my speculation. About 10 #’s over 370 weight limit.
