so i just had a new light weight clutch installed an when im cruising if i up shift an its at low rpm like goin 45 in 4th at 2500rpm an floor it i get a really big vibration, this only started after i got the clutch any ideas?

 

why would you upshift at low rpm and then floor it??

 

no reason an i dont even have to floor it any throttle will do it

 

Im gonna guess that your lightweight 'clutch' (I assume you mean flywheel), by virtue of its light weightness, doesnt have the dampening characteristics you've grown accustomed to with the dual-mass stock clutch. Its like putting stiff springs on a car and wondering why the ride is bumpy.

 

i understand the diff between the stock flywheel an the lightweight but using a lightweight one will vibrate so bad it shakes the entire car?
