      Just had a ECS Ra4 clutch conversion installed today. Now I have a horrible rattle sounds kinda like a bad bearing On the test drive I only heard it at low rpm under load. Back at the shop you could hear it while reving it would go away with the clutch engaged. Shop was closing so had no time to take anything back apart. Any ideas what might be wrong.

      Install was done at a trusted shop car is still there.

      What you are experiencing is clutch chatter. This is very normal when you have a light weight flywheel installed.

      Nothing to worry about.

      Will the sound go away or get better?

      You had them throw a new throwout bearing in it while you did the clutch correct?

      Actually What you are hearing is not clutch chatter. What you are hearing is Gear chatter. Why? Well I am assuming you had a single mass flywheel installed? if so here is what I know. I did the same thing I went from dual mass Flywheel to an aluminum single mass flywheel that only weighs 10.1lbs exactly. the difference between the stock and aftermarket ( SPEC ) clutch and flywheel setup is almost 13-14lbs give or take. and I had the exact same noise coming from my transmission it went away during acceleration or with the clutch pedal pressed in. at idle it sounded like a chattering noise. Sound like your problem? well if so here is why when you take away weight from a perfectly balanced crank shaft that is designed for a 23lb+ Dual mass flywheel you are taking away a lot of weight so therefore what is happening is the gears are fine and everything is find but the vibrations from the crank are not getting absorbed completely so they are vibrating threw the transmission into the gears making them vibrate causing your chattering sound. I drove my car from CA to NC and Back with no problems and 50k miles on this set up with that annoying noise at idle you will be ok. In fact my info is coming from a SPEC engineer only because I emailed the guy and this in more or less words is what he said hope it helps

      Oh and no the sound will always be like that. Drive it man its fine the only way i know of getting rid of this noise is to go back to your heavy ass dual mass flywheel. you can upgrade your clutch disk and pressure plate if you want but the flywheel likes to be stock on these cars
