I have a 2006 Infiniti g35 with 74k miles and my clutch has progressively slip worst and worst. I was wondering if I can change the clutch and keep the stock flywheel? I want to keep my dual mass and dont wan't to get an aftermarket light flywheel and cause 'chattering noises.' What is the pro and cons of keeping the stock flywheel vs a new light one that will chatter.

 

Problem is to do a clutch job correctly you need to resurface the flywheel, The stock dual mass cannot be resurfaced correctly as the top of it floats and makes it nearly impossible to resurface flat/true.

There is no pro to keeping the stock flywheel,
Advantages of a single piece lighter flywheel is it can be resurfaced, it will free up lots of power.

We stock the new South Bend Clutch "quiet" disk clutch kits which really help to keep the trans chatter noise to a minimum.

I know people that can (and will) machine the stock dual mass flywheel accurately and safely. However, the real reason the stock flywheel shouldn't be resurfaced is because it has moving parts and those moving parts wear along with the flywheel. You might get some more life out of the flywheel but eventually those moving parts will give out and you will have problems.

My opinion on going with the single mass flywheel is that excess vibrations are going to be transferred to the transmission and generally speaking excess vibration equals to accelerated wear.

 

If you're going to do it, do it all the way and get an actual light weight fly

 

You should never resurface the stock flywheel, There is absolutely no way to keep from getting the cuttings and abrasive mixture from the surface grinder into the machined, floating part of the flywheel which will cause catastrophic failure later. DO NOT resurface the stock flywheel, ever.
