NOT HAPPY! after seeing so many people fitting ZM3 LSD bushes i thought i would get one for mine. So i took it to an engineer today to have the new bush pressed in.
He took the old one out and measured them both and said '' sorry but this new one is 1mm to big and is too wide. I would run a big risk of cracking your casing, that wont fit''.
I have heard loads of people have fitted these!
Whats going on?!?

Strange. I've also heard of this as a common upgrade.

That seems a little strange.
I fitted a genuine BMW Z3M diff bush to my E30 medium case, I just tapped it in with a small hammer!

drops straight in, fitted loads, only fits in one direction though as its slightly oval
He's not left the metal ring part in from the old bush has he ???????

Other option is a Powerflex one...but Z3 one should fit...as whole Z3 back casing also fits the E30 diff/car

I've no pics, but the wide bit (in the non-symmetrical plane) sits at 12 o'clock, if that makes sense?

The new (Z3M) bush should turn about 3ish degrees anticlock looking at that pic.
