I'm pretty sure there is just some inherent slop in the 8.8" diffs themselves.  It doesn't affect driveability.... there is just a slight clunk from a start.

^Exactly. You can hold the axles still with the E-brake but still move the drive shaft back and forth maybe 10-15* of a turn.

You don't... it is the transmission that is doing most of the clunking and has the slop in it. The half shafts can have just a bit of slop but that is normal. The OEM gear backlash in the 8.8 IRS is a little on the loose side as well. You can tighten up the backlash and that will help a bit 

My brother's 6 speed Camaro SS makes the same clunking noise my Cobra makes from a stop.

All in all it is not that bad.

Yeah it's not very noticeable unless you are paying attention to it. Although I will say I never had any slop in the system with the Mazda diff. There was no clunk until I installed the 8.8.

It's a very small price to pay for all the positives that come with the 8.8 swap.

So tempting, but bad timing.  If you still have one in a month I'll probably pick one up.
