Vorshlag has been making spherical shock mounts for many years, for a variety of chassis: S550 Mustang, Corvette, many BMW applications, NA/NB Miata, 86 and more. These rear mounts are specifically for the the 2016+ 6th Generation Camaro chassis. They are made in house here at Vorshlag and feature the same over-sized spherical bearing you'll find in our camber plates. These shock mounts are big, beefy, and as strong as a tank. Removing the stock rubber top mounts and replacing them with spherical top mounts will improve suspension articulation and movement.
Even when these OEM rubber shock mounts are brand new they have a lot of slop from the rubber bushing. This rubber will compress and slow down damper reactions to vertical inputs in the suspension. Going to a spherical mount fixes all of that.
More importantly, the OEM shock mount's rubber bushing is held into the aluminum mount by a steel washer, which is crimped into the upper edge of the casting (visible above). This is prone to failure, especially when you convert the rear to a coilover shock. It acts like a "fuse" and when higher suspension loads pass through this it can "pop"...
This is because the OEM mount is made to only see damper loads, but when you move the spring to the shock the mount then sees the full suspension loads, which are an order of magnitude higher. Replacing the "fused" stock mounts with a properly engineered, spherical top mount adds real reliability to a coilover rear setup.
We developed these mounts after noticing that many shocks can bottom out (run out of "bump" travel) when using a spherical rear shock mount made to match the OEM heights. For a lowered Camaro on coilovers that sees road course, autocross use, or even street use, the additional bump travel is very worthwhile. After testing this solution we are very happy with the design. We strongly recommend these when using any coilover rear shocks on the 6th Generation Camaro chassis.
UPPER STEM DIAMETER: These shock mounts are designed to work with virtually any rear shock that is made for the rear (that isn't an "eye" style upper). We use different upper and lower bushings (spool pieces) to adapt the big 3/4" ID of our spherical bearing to the shaft sizes of the very top of the rear shock. YOU have to tell us how to build your shock mount assembly by picking the proper upper stem diameter of your rear shocks at the drop down menu below.
The part we need to know from you is the very top - which will have a 10mm/M10 threaded or a 12mm/M12 threaded upper shaft stem. Typically an OEM or non-adjustable shock has a 10mm shaft and an adjustable aftermarket shock has a 12mm shaft. The shock mount sits on the shoulder or step where it goes from the big diameter and necks down to the small upper stem diameter. See the images below for a better explanation. If you are unsure about shock shaft upper stem option to choose, please email or call us.
