limited slip diff

[Fritzmeister]

I would like to install a true limited slip diff in my M Coupe. I understand that there is a plug and play diff from another model that will fit. Anyone know that model?

What do you mean by true as the come with a LSD as standard

As above the M Coupe comese with a "true" LSD in clutch pack style. The non-M Z3s came with a Torsen diff which isn't as good on track.
