i find it interesting how he says they actually lengthen the traction rod as opposed to shortening like most people. I think when you slam a car it moves everything forward as it is so making the traction rod longer puts it all back where it should be. ima mess with mine with the coilover disconnected and see what it all does.
from what i understand, lengthening the traction rod actually increases wheelbase, if not by much. This helps in mid-drift stability. but you are right as well.
