Richard - I think you make a valid point about the degree of "lock" across a limited slip diff.

What I see here in the UK, where jaguar rear ends are almost the "norm", is that folk take that diff out of a 5000lb jaguar and fit it unmodified into their 2250lb Cobra.
The slip characterisitics dialled into that diff from the factory are for that heavy, long wheelbase Jaguar XJS or whatever, not a Cobra.

Those that know, realise that you can play around with the clutch packs in the diff to get reductions of 30 or 60% in locking action, just by rearranging the driven/driving plates. Also, more fine tuning can be done by changing the belville washers which provide the spring clamping action.

So I guess that if I were to finesse my point, it is that LSD with too little "slip" is not a good fit with the Cobra, and WILL make it a tougher car to control.

Craig - how does your car feel on the street with that locked spool rear end?
