shift bumpers
i was at a dealership to other day with a friend who was looking at a new regency truck, and we got talking with a younger sales man who has a 99 gtp, and he was telling us about removing the "Shift bumpers" as he called them to make it slam gears faster and harder? is he making this sh*t up or can this be done....if so how?
