The locker noise is subjective I think, some might think it's unacceptable for a street car, others might not even notice it. I have Ron's 40# springs in mine. During street driving, you will notice it clacking a bit when turning while backing up mostly. Once under way going forward, it really doesn't make much noise at all. You never hear it engage and only once in awhile will you hear it disengaging when entering a slow turn in a parking lot.

Driving wise on the street, the only thing I notice is every now and then it'll kind of pull one way or the other just a bit, never enough to upset anything....it's just something the you notice about how the locker acts just a bit different than a clutch or other type of posi.

On track, it acts completely different than a regular posi...and it makes more noise too. I still haven't figured out why the noise level varies, but when the locker disengages on corner entry, it can be anything from unnoticeable to a clang loud enough you think you dropped a driveshaft. I believe it has to do with how much tension is built up on the mechanism just before it releases and whether there is compression or acceleration input onto the pinion. If you are steady state when it releases or accelerating just a bit...it's not a big deal, if you are decelerating under engine braking on turn in when there is lots of grip (like on concrete) it'll bang pretty hard. You can clearly hear it in some of the runs in the video above.

Regardless of all of that...if you want spool like traction on corner exit with a diff that will also release for easy cornering on street or track...this is the ticket.
