aussie or detroit. if you learn how the locker handles you wont have any issues with handling, tire wear may increase slightly but thats a small price to pay. im ordering an aussie for my front in a week or 2 ive got a detroit rear now and on the road i rarely notice its there unless i stomp the gas in turns or engine brake in turns . a locer will lock only when power is applied so its best to coast through turns as much as possible.
