I can not tell you how much difference this makes for me. With the stock LSD if you hit it real hard, the back would step out very easily. I have even done two 360's because of the back coming around. With the Quaiffe in, you can hammer it and it doesn't step out as quick (I have not done a 360 with the Quaiffe in it). IMO, there is a big difference. Now I will say I am at about 360 hp so it makes a bigger difference for me. if you have 280, it might not matter as much. Now If I were Sky888, or anyone in that hp range, I would have one for sure.
