The caliper is the same as the ats. Theyre from the 2.0l 4cyl camaro. So in theory you use the S AND S engineering kit and they bolt right up. So they'll go on the cobra once my inserts are done. Gm lists them as different parts but I'm pretty sure it's just because the paint. I can confirm the pads are the same, rebuild kit is the same and the without inserts the holes do line up. So it's another caliper option if you're browsing the junkyard or eBay
And its very possible I'll have a solution to spending 175 bucks on the inserts from s and s and maybe cost around 100 bucks very very soon
