Rattle Recently started in Neutral while in Idle
 

Rattle Recently started in Neutral while in Idle on my 2017 BRZ, but I just installed a Complete ACT HD Clutch kit with the new OEM TOB with the new grease that does not dry out and burn up and a Perrin Transmission support block and a Perrin Fork. My idle goes down to 800 and it's there. I'm removing the Perrin Block (which lets you hear every gear shift in the cabin) and having my tuner (James Martin) correct my idle.
The ACT HD clutch has a light weight fly wheel and I knew there was probably going to be some chatter, especially for the first 1000 miles.
I am sure that nothing is lose in the clutch


Will see if this makes it go away.

Any updates on this? Mine started doing the same...
I noticed that many people with this issue have Motul oil...
