CAMARO6 - View Single Post - Will I miss the ELSD or really notice the weight?

I'm still confused and a vert Zl1 manual seems to very rare. Does the loss of eLSD mean the vert is running the same 8.6 diff with the standard SS clutch base LSD unit? That is what I always thought, but there are several things that confuse me.

Facts supporting the Zl1 vert using an SS diff:
1) the weight reduction would indicate the vert manual is running the smaller SS diff
2) at least on Zl1 manual shaft MM6 is the same trans as the SS, GM uses the trans code to id the driveshaft (so I'm not saying the ZL1 has a SS trans) I am saying the manual vert Zl1 runs the manual SS driveshaft: 84306999
3) Looks like the F carried: PN 84627771 is used on the Zl1 vert manual and on the plain manual SS

On the other hand:
1) all ZL1 left side axle shafts are the same unit so that would kind of indicate that all ZL1s run the same 10.9 diff (even though it is possible that the SS diff has near the same diff to wheel hub stub length) PN 84372865. The SS has a different left side part number 84309455

2)The ZL1 non-vert and 1LE have the same right side axle shaft pn 84309457. The SS manual has a different shaft pn 84309456 I don't show any listing for a Zl1 vert shaft. i.e. it must already be listed meaning it could be either of the shafts above so that offers no indication if which diff the vert uses.

It is VERY hard for me to believe that the vert manual Zl1 if indeed it is equipped with a SS 8.6 diff, uses the stock SS right side shaft.

The only reason I'm asking is I think a great upgrade for the SS would be a 9.9 diff and axles with a standard LSD. Gets around the issues of GM electronics programming. Brings the OEM HD stuff to the poor slubs.
