An LSD is all about performance, not quietness and comfort. This is meant to be a sports car not a sofa on wheels.

Viscous units do wear out and become totally useless open diffs. Mechanical units perform at spec for much longer and particularly don't suffer immediate failure at high temps.

Totally disagree about the cost angle. I think it's becuase the Z is NA and not turbo like a Silvia.

That's why it's not on my list of models that had a mechanical LSD.

Apologies for the rant...I just can't understand why Nissan only put real LSD’s in the turbo models and not the NA ones.
