Hi all. Today I got my blob wrx back from having a new clutch fitted. I had the flywheel skimmed and the car drives well at standard plodding revs. I was told to take it easy so I have driven it like a nun.

If I put clutch in and rev the car, I hear and feel through the clutch pedal a vibration between 3200 and 4000 rpm..

If I slowly pick up revs when driving also I hear and feel the vibration slightly at same rev range but its more noticeable when clutch is down and its picking up and dropping revs quickly.

I have only done 30 miles since it was done but I am worried it may be my flywheel (seeing as its strongest when clutch is down)

What do you think? Take it back?
