Hey I just installed a fx300 clutch master clutch about a month ago and every time I go above 3500 rpm in 2 and 3rd and let off the gas it starts to rattle if I shift into neutral it stops ? Checked all the heat guards on exhaust that's not it help!

 

did you change the throw-out bearing?

 

^^ just about to say the same thing, did you brake it in before Doing Hard Pulls. or did it Just Start ding it out of nowhere. it might need to be adjusted or something.

 

Yeah that sounds like a throw out bearing, I purchased my car with a new clutch but apparently they neglected to change the throw out bearing, annoying noise lol.
