ZL1 1LE Rear Aluminum Subframe Bushings
 

Does anyone have them not installed and can take some measurements and pictures for me? I have a 2017 CTSV and am trying to see if they will fit my car.
Thanks in advance.

I would never use a part made for a specific vehicle and "try" to see if they would work on a different car. Especially a part that is attached to the subframe, even if it was built on the same chassis.

Does GM Performance or the aftermarket not make specific solid bushings for the CTSV?

While I agree with you, think about what we are talking about. I want to replace my rubber, fluid filled subframe mounts which your SS didn’t come with from factory either, for solid aluminum. What exactly makes a piece of aluminum ok for a Camaro and not ok for my V? What is the difference if I had a company custom cnc aluminum bushings for me?

And if GM or the aftermarket made them and I knew about it, why would we be having this conversation?

So if my subframe mount holes are ID 59.95mm and my factory mounts are 60mm and the ZL1 mounts are the same size what would the issue be?

I would be willing to bet they are the same...GM likes to make money so I doubt there is anything "CTSV specific" for the cradle attachment point. Have you checked to see if the stock bushings are the same part number? I do know they take the same TTY cradle retaining bolts which definitely points to the likelihood the bushings are the same as well.

Yeah I checked and the part numbers are not the same. That’s why I wanted to try and get some measurements. I hope they fit, No one makes any kind of bushings for my car.

While true, the cradle in the ZL1 1LE , ZL1, and SS 1LE, and any other 6th gen Camaro are the same, so they are interchangeable. Also, per GMMP, the solid cradle bushings I got are an approved upgrade for the SS per their catalog.

Maybe it is the same in the CTSV too, I am just saying for me for such an important attach point, I wouldn't personally risk it.

:help:
I've been looking into the possibility of this setup for my convertible. I'm looking to see if I can hopefully come across anyone that has knowledge of the convertibles rear subframe, and might know if A) The bushings are the same size, and B) If the convertible would benefit at all from the install of the ZLE/GMPP "upgraded" solid bushings? Thanks

I should be receiving the GMPP bushing this week i will post the measurements.

Message me with what your looking for. I wont install mine until the winter time.

Hopes this helps

i still want these for my car but parts plus labor its probably going to be $1000 or more haha

They are tuff to find but I believe its going to be worth it. Supposedly I got the last set in all the Chevy dealers in the US. My local dealer searched all the dealers inventory and found one in UT for 472 shipped. So not srue if the kits are getting harder and harder to get but I would jump on it incase they stop making them.

yea i know i heard that i just dont want to buy them and then just sit on em

They were discontinued for a whole then brought back. Production was moved from the US to China. So the lack of parts is likely due to the current worldwide situation.
