First issue
The wheel speed sensors are different on the camaro. I was already aware of this ahead of time, here is a quick pic of the harness connector. I am hoping to pull the connectors apart and swap them over. If that doesnt work ill simply cut and solder the wires.

I cut the G8 connector off of the cradle and soldered each wire onto the Camaro harness.
Passenger side G8 grey wire goes to Camaro Brown wire
Driver side G8 grew wire goes to Camaro Tan wire

Pretty straight forward. Jack up the car and take the back wheels off.

Drop your exhaust.

Disconnect your drive shaft-
pull one bolt, put the car in neutral, rotate the axle to turn the shaft until you can reach another bolt, put the car in Park, remove the bolt, but the car back in neutral to rotate the shaft again ect......

Pull your calipers off and hang them off to the side. No need to disconnect the brake hoses.

Pull your ebrake cables off the knuckles.- Pretty easy they hook onto a tab on the back of the knuckle.

Unplug your wheel speed sensor harness, its the grey connector near the gas tank on the passenger side.

Remove the lower Shock bolts.

Support the cradle with a jack directly underneath the carrier. Remove the 4 bolts that hold the cradle on. 21 mm i believe. If these haven't been removed before they can be a pain. Be careful, if the they are being stubborn use a torch to heat the bolt up to melt some of the factory locktite.

Slowly lower the cradle with the help of a friend on either side to balance on the jack. It balances pretty well on the jack.


Tied Up the Calipers

I got my rear cradle install with some friend in about 4 hours today from a 2015 Camaro as. My cts v rear rotors would not
A few more things.
It appears that the new cradle lifted the back of my car a bit. Maybe 1/2" or so. Also, the new setup is approximately 3/8" narrower than the g8 setup, we measured rotor to rotor.. I was actually hoping this was the case. I have been fighting a rear rubbing issue with my wheel combo. I hope this fixed the issue


The Camaro bushings are huge! And they stick up quite a bit out of the cradle. I believe this is why it raised my car up.


The brake hose brackets are different. the G8 has those silly black plastic turn-in washer thingys. The camaro uses at bracket on the hose that bolts to the upper control arm. Either swap the hoses or figure out a way to support your g8 hoses. If you dont already have brembo calipers like I do this swap would kill 2 birds one stone.

The parking brake works just fine. I reused our parking cables, they hook right up to the camaro knuckles.
Ok so I did this swap

So today I did this cradle swap off of a 2015 Camaro SS with only 15k. Overall is was really easy with two friends and four hours we were done,a couple of things my cts-v rear rotors would not fit due to a smaller diameter parking brake area,then my Giovnna wheel hit the rear caliper on the camaro setup so a spacer was added,then I had to notch out the cts-v calipers for a proper fit but the main thing I need answers for is a clear description on how to properly split and wire the four wires from the camaro to the four wire on the G8 abs harness because now I have a abs fault.
Thanks in advance oh the 3.45 gears are awesome!

Buy the Chevy SS rotors. They will solve your ebrake issue.

I made an adapter harness for the ABS, but I think you can repin the Camaro wires into the G8 connector.

I'm very curious with the change in geometry and the raising of the rear...how did the 4 wheel alignment go for everyone who did this swap?

Fantastic write up OP.
