These things sound like the Detroit locker, that is in my friends series 2 rx7 with 13B turbo. This detroit locker is inside a custom shortened 9 inch setup.
I have only driven it once. Thant was enough. You either drive it hard or not at all. The locker snaps on like nothing I have ever seen before. You can be idoling through a carpark, and all of a sudded the rear end jumps and you are facing the wrong direction. Very scary. Deffinatly something you do nopt want in a daily driver.
