To be fair, we'll all scratching our heads if 1.0 to 1.5 grams less weight on the top of the chassis could make this much of a difference but it was worth stating either way. This racer runs the less common Corvette body but if a lower center a gravity is king... this would make difference.


Any mathematicians care to take a crack at the effects of removing 1.5 grams from a 180g car from the top?
I doubt that the new transponder is what stopped the traction rolling. The racer's tires probably weren't broken in when the old transponder was used. The 1.5g savings is only .83% of the total car's mass.

However, the new transponder looks significantly smaller than the previous version, which is a good thing!
