Hello,
Long story short, I have a 06 gt 5 speed that I’ve had clutch engagement issues with. I replaced the slave thinking that was the issue because it was in 2 pieces (which I now realize was due to the slave/ throwout bearing over extending.) I’ve come to the conclusion that I need to shim the slave. The clutch has 5k miles on it, and I don’t have the original clutch to properly measure what size shim I need. The clutch I have on there now is the Exedy Mach 400 kit. I have a pack of shims...
