I have a 2017 build. The car was built with the taller springs. The dealer has no issue replacing the springs but says they are on back order. I started to look at the GM parts vendors online. When you punch up 2017 ZL1 none of the schematics show the Part Numbers, 84312736 & 84312735, called for in GM document #17-NA-208. Further the part numbers for the springs for the 2018 build are different (presumably this is the same spring, do part numbers all change for each year?). Finally if you punch the part number into the search function of the parts dealers the part comes up. This is all very confusing.

I am going to have Moreno camber plates installed and given the fact that the springs are so cheap I thought (if I could find them) I would just buy them myself and install them at the same time as the camber plates.

Does anyone have any insight as to what part to order? From where?

Thanks

Thanks. The dealer is working on getting the springs. I would just as soon do myself. I am really looking for the part numbers.

84312735 is the correct part number of you have a couple. That's the front springs for the coupe. The number ending in 36 is the convertible fronts. I had this done a while back with great results.
