Going to try and not touch the pistons, I knew and didn’t plan on the speed pros being light pistons just didn’t expect them to be 25grams heavier than stock, figured they would be close to stock as I have read a lot of people run those with stock rods to avoid balancing. Knew the rods should be within a few grams of each other, but 14 grams total weight difference between the lightest and heaviest seems like a lot especially since the pistons are 25grams heavier than stock
