instead of one wheel biting more on take off and on general accelerations it distributes the power equally to each wheel giving it monumental grip off the line and grip and power out of the bends. deffo a good thing imo... just not sure about one on a std box... i've gone through one already and have killed a gearbox on all of my cars... i have a tendency if i'm gunning it to change gear and slam it in far too fast and hard... got the Willy to spin slightly a couple of times in 3rd with Wayne in the car :oops: hehe
