I don't think so I just called today. I ask and was told to buy a 3:42 gear set up from GM.
Regroup on this RPM should have something out for us within the month of Jan/2017.

We have adapter C6Z diffs into them now. We broke 2 C7 Diffs in one of our cars and have since installed a Level 4 RPM C6Z diff and its been good since.

I am sure it broke from 2 years of abuse at the track and massive tire shake last time out at the track. We are woking on different gears set up and options from the c5-c6 cars.

Frans96ss - Could you provide more information on how the adapter works, or if this is a part that you manufacture and sell to work with C6Z diff that you're currently using?

new supplier of rear differential assemblies to GM for the C7 models, not the same supplier as the prior generations, so some unexpected "growing and learning pains" to be expected.
another scenario is that these meet original GM specifications, but vehicle produces more torque, or load than originally anticipated and originally designed for.

I also broke the spider gears in my 2015 Z06's A8 differential after a year of drag racing.Instead of repairing the unit back to stock specs or replacing with another stock unit, I modified a stock unit to use 4 spider gears instead of the 2 it was designed with. It has been working excellently , with many passes since the modification, including completing Hot Rod's Drag Week 2016 event.When I did the modifications I started with a complete carrier assembly from a Z51 in order to take advantage of the higher ratio (2.73 vrs 2.41) of the Z51. I have some pictures and can explain the process and procedures I went through if anyone is interested.Ed Urcis

Ed,
I for one would love to hear more about the 4-pinion spider setup, I have done them in fords and solved the issue. Did you use a block to support the inner end of the 2 short spider pins or did you machine flats on 2 long ones so they interlock?
I know for certain I am going to have issues here, I may not get my 1.29 60 but the 1.32-34 is coming....
