Dremel the little ridges inside the casing down around where the diff sits. Did mine the other day and no more issues

Yes you will need to push shims on all 3 motor mount screw!

In this picture you can not see the 3rd shim.

My car is running well so I did not want to take it apart to show you:p

This is exactly the same as i had to do today, the screws were coming out to far and rubbing a groove in the slipper plate causing the stiff feeling. 3 x .5mm shims and it's all good.:)

I saw Mattr try this today then saw how much he tightened the screws :woot:, Looks like a mod Ill be doing as well. Nice find fastfilli

Just be careful what order and how much you tighten each one, i.e. go round in turn, snug them all up, check the box, extra half turn each, check the box, and so on. Until you think its tight enough!

I also found that my layshaft spacer was starting to crush as when i put the spacers in, the slipper was dragging on the motor plate, time to buy a hardened one!

Plus another one for fastfilli's mod !!
Just done it on my 210 & now the diff is SOOOOOO smooth !!

Nice one ! :thumbsup::thumbsup::thumbsup:
