I know the camber plates fit fine as I have been test fitting. The catch is that the GC plates recover about an inch of travel moving the shock up and higher in the shock tower. That threaded portion of my shock shaft is protruding from the top nut of the camber plate. That will require me to open up the shock tower. I'm curious if any of you have experienced any side effects from opening it up. As for noise, I really didn't notice much (5%) with the Vorshlag plates and they were metal on metal as well. I don't expect to have any additional NVH with the GC.
Here is an example of what is required when running coilovers that protrude the opening. This is an RS3 shock tower that was punched out using a conduit punch.
I know I could space the shock down but that eats up precious bump travel.
The reason I'm asking about strength is because a fellow TTRS driver hooked the backside of a track corner curb and that caused his suspension to push his 034 camber plates up into the tower hard enough to damage them. I have to wonder if those domes provide any rigidity or strength and how this impact would have been different if the towers were modded. If you look closely at the second pic, the shock was enough to cause paint to flake off the dome!
