LSD80% VS LSD40% M220 "Factory"

[_gonbau]

All LSD’s in the early cars were 80% into the mid 70, then they were 40% thru 84 with multi plate diffs that could be adjusted. Then in 85 they became non adjustable 40%. If you didn’t like the locking value of an early diff you would adjust it, as there were 4 or 5 different adjustment settings. Don’t try to make a mountain out of a mole hill, it wasn’t that complicated. I did a 72 ST some years ago, it had 80% diff. The LSD option was not that common, mostly special order. The dealers I worked for never ordered them for cars they were flooring, thought they were dangerous.

I have just seen this response, and it does not answer my questions. We have observed that in 1972, different LSDs with 80% and 40% could be installed. Does this mean that the factory differentiated them when installing them in the vehicles in some way?


I don't think my question is difficult to understand. While I understand that this topic might be repetitive, in this post we have seen different opinions that have been clarified with documents.


It is known that LSDs were not common, and they were usually requested if the driver wanted better vehicle performance. From my perspective, LSDs could be dangerous. In the case of our vehicle, the second owner, who had an accident, may not have been accustomed to them, leading to the loss of control. I suppose that at that time, installing an LSD was an uncommon upgrade that would have drastically changed the vehicle's handling. However, I am still wondering how the installation of the LSDs was differentiated. These questions may never be answered.
