Casaleenie - that just plain ain't helpful. But I suspect you know that already. 'nuff said.

However - since we are talking about the engineering aspects of Cobras and the impact of that on their safety for street use, here is a particular "thing" that bugs me - Limited-slip or locking diffs..

To my mind, LSD just is not required for a street-driven Cobra. Absolutely necessary for track or drag strip, yes, but not for the street.
If you guarantee that both rear wheels will lose traction together with injudicious application of throttle, you are also guaranteeing a total loss of lateral stability.
Not something you really want if you are tight for space, or committed to a corner.
I might lose out on outright traction with my open diff, and for sure it annoys the heck out of me to spin away all the power from the inside wheel on a road course corner, but my car is 95% street driven, and I much much prefer a rear end that stays put to one that gets squirrely if I misjudge things (and don't we all sometimes, if we are honest).

No - I would rather that just one rear wheel breaks loose, leaving the other with some semblance of lateral grip.

JMHO, of course. I should be very interested to read the opinions of others with far better driving skills than I, and for sure there are a lot of them. Turk said it well elsewhere - I drive this car scared for my life. Might live a bit longer because of it.
