Clanking noise with clutch out (newer Spec 3+ clutch)

[beater986]

Hi folks,

Ever since the installation of the new Spec Stage 3+ clutch, this car has been very "clanky"/"knocky" with the clutch pedal out. It happens generally when the engine is warmed up, but can sometimes occur on cold start. It sounds like a throwout bearing (which was changed with the clutch).

I have attributed this to spec clutches being super noisy; however, is this possibly a symptom of IMS? I imagine that the IMS knocking would be consistent, but figure I'd ask.

Thanks,
