If you have Z51 you can expect ~24 hours labor. The C7 with Z51 is much more difficult than the C6. I had my stock clutch replaced last season. My installer said it was not difficult just time consuming.

What about the Z51 makes it more difficult than base? If this is true I am going to limit my use of launch control and avoid the strip to make mine a "lifetime" clutch.

If you have a high performance car, you should expect a clutch to be expensive to replace. Just like tires and brakes, it is an expendable. You have to pay to play.

First they need to remove the trans, rear and torque tube. Lots of things to disconnect.
In a C7 Z51 that includes trans cooler and dif cooler lines and the sway bar. Base car doesn't have these. May be some extra with the ~3000 psi electric pump for the eLSD.
The C7 has a dual disk clutch so the parts will be more than the C6. Assume it would be logical to use a new throwout bearing assembly and bleed that system.
Would sure want to have someone who did it before I was the first! Always learn from the first try. Like most instruction manuals there are usually a few things not covered or covered poorly!
Another good reason to sell my September 2013 built Z51 C7 and buy a 2019 GS!

Agreed, you'd want to have a seasoned tech do this. Get something in wrong, or forget a bolt or something then have 3 more days work to correct it. This could be a nightmare job for a non-expert.

The only mention of clutch issues I have heard of was at Spring Mountain. They said they had to replace a few until they started teaching people to start rolling with out applying throttle until the clutch was fully engaged. It's simple to get this car going without slipping the clutch. I am anticipating never replacing it.

My shop said there was a lot more involved with the coolers etc. They had done a lot of other C7's but said my Z51 was much more time consuming. I paid a set price so the shop had no reason to keep the number of hours to themselves.

There was a show... TWO GUYS Garage that showed how they did a clutch on a C5/C6. A Z06 as i recall, so should be no different for a C7, Z51 or not ( IFF you do not drop the torque tube /tranny ) They used a series of jack stands under the driveline so they did not have to disconnect all the cooler lines, I believe there should be enough flexibility in the lines to do that.

That said, I've heard as a rule of thumb, look at the cost of an auto transmission option on a car, and figure that is what it's going to cost for your clutch, more or less.
Good luck.

Someone had fried their clutch on a 2014 C7 at 16k miles while at a drag strip, and they showed me the invoice of what he was charged
