Well, that sucks. Pulling the trans out of this car is an absolute nightmare. Here is a video of how much it is shuddering. The shudder translates all the way to the wheels.
Yeah, that’s a clutch issue. I don’t know what your spring load is but it’s got to come down or you need a different disc. My off the top of my had guess is anything over 2000 pounds and it’s going to shake like a dog pooping peach seeds. It will probably take less.
I’m not a big fan of ceramic, velve-touch, dual friction or any of that trick of the week Crap for a street car. Either use a nice, high performance rag disc or you need to step up to sintered iron. And the issue with sintered iron is the exact same issue you have...it can’t stand high plate loads.
You’re kinda stuck. Do you remember what the pressure plate is?
