So I've just finished installing the following: Exedy OEM Clutch Gruppe-S Lightweight Flywheel OEM Subaru Throwout Bearing/Clips ...all for an 06 WRX. This is a pretty well-documented plug and play swap with the OBS/RS transmissions, and the install went in without a hitch. For the second time in my life, I didn't break anything (though my ability to crossthread bolts continues to amaze even me) I'm having no problems depressing the clutch, nor am I getting any weird smells. I can shift into gear just fine. However, at the very beginning of the clutch engagement point, up until maybe about 50% of the way down, I get a faint whirring noise. The best I can describe it is that weird noise that a vacuum cleaner makes when it's really close to a carpet. Anyone ever heard of such a thing happening? Any idea what it is? It doesn't seem to be affecting driveability at all, but I'd like to make sure it isn't an issue. Thanks!
Yep. New Throwout bearing and pilot bearing. Apparently it's just lightweight flywheel noise, though...?
