Any Cobras built with open diff?

[Morris]

I’ve used many different Differentials over the course of time......the welded up diff was great for autocross.....the limited slip requires a lot of maintenance to keep it working properly......the Salisbury Diff was the same way but the ramps not the diff allowed you the control how much drive you got on both rear tires.....and finally we are using the Quaiffe diff in the KMP259 and it works the best as it allows the rear wheels to unlock and turn in at the appropriate moment.....then as you accelerate towards the apex, the rear wheel drive the vehicle but not so much to push you away from the apex.....by the time you push the throttle down to the floor the Quaiffe diff locks up and drives the vehicle past the apex to the exit of the turn.......even in a straight line the car will jump a bit to one side or another....but then it catches and pulls straight forward......it is better to drive smoothly around the corners......and the Quaiffe verses the open, Welded, LSD, or Salisbury is by far better then the others.
