So I've got this 150-ish k L36/T5 combo that a 96 Camaro is donating to my Porsche 944 project. I'm getting ready to stuff them in for last mockup/first get it to run. Therefore I want the clutch/flywheel/throwout bearing to be in good condition. When I opened up the clutch this is what I found. The shiny flywheel bolt heads correspond to the shiny clutch tabs just inboard of the springs. Does anyone know what caused that? Will it go away if I just order a new flywheel, new flywheel bolts and new clutch?
Also - if I order a new flywheel, are there any special concerns with balancing it? I thought I remember reading that there are V6 specific issues with balancing flywheels - but maybe that's just when swapping from an auto tranny to a manual one.
