Mechanical rattle when setting off in low revs in my 370z...

[Yorkshire_Zed]

Ive just purchased a 370z,i love the car - the only thing thats worring me is this loud metallic rattle when i pull on ff in low revs in 1st or 2nd - its fine after around 1k revs. I cant hear anything rattling or loose underneath. I contacted the previous owner and they said its single clutch conversion kit,that’s the noise it makes from dual mass to single mass clutch kit.

 

Is that likely what it is? I have read on another site that its probably that - to do with an aftermarket flywheel. It does sounds pretty rough in my ears, but is it something you just put up with?

Did you not drive the car before you bought it?

 

Fitting a SMF in place of the factory DMF usually creates a "rattle" at low rpm.

 

That is because the SMF does not have any transmission damping properties.

Single mass is quicker and more responsive on pick up. But yeah you will get chutter.
