Lighter is better? Only if it holds up under the duty cycle.
Last fall, I was at Phoenix for a little driving, (Cup car) and Honda was there to do some testing. (F-1) I did have my camera, but as I walked through the garage area, you would have thought I was a terrorist.. Guards everywhere.
(Or was that gourds?)
Anyway, they ran me off... Doug got a ride that day as I recall.
