I certainly agree that it's unlikely that a lighter battery will do much to improve handling or launch times, but it is interesting to see how that modification would change the weight distribution. Not surprisingly, the right-front corner is the heaviest on the stock version of the TH (obviously with no driver or passengers). I've attached the weight distribution graphic created by the SavageGeese YouTube channel. If the Darrell Cox battery (~42 lbs lighter) is used to replace the stock version the right-front corner weight drops down to 1,520 lbs, which would make the right-front corner only 45 lbs heavier than the left-front. Of course, you then put a driver in the driver seat and the left-front is much heavier. Anyway, I just thought someone on here might find the weight distribution numbers interesting if they haven't already seen it or had their TH weighed somewhere.
