hi all, i was rooting round under the bonnet of my bb4 earlier, i noticed that the gearbox has a sticker on it with the barcode and the code m2A4, wich i thought was a non lsd gearbox, if im correct mine shold have the m2B4 gearbox with the lsd? it feels like i has an lsd in i as it will spin both, is there something a miss or am i bieng a bit of a tool?

BB1 = 4ws
BB4 = 2ws

That IS the only difference
Everything else was optional.
