Thanks for your thoughts Eric.
“… because more mass is available to shift about the kart to optimize performance compared to a heavier compatriot.”
You’re referring to ballast here?
You’ve talked a bit about the height of the driver in the seat. I wonder if I should try a seat cushion again to test the effect of raising the COG on unloading the inside rear.
My answer to a weight disadvantage is to use the slight grip advantage it confers to do less accelerating than the other guys.
Appreciate your thoughtful answers.
