my e30 has a rb25det in it 300.9bhp.
ive just got an uprated bmw LSD which has what I presume is a standard bush in it.
its flexing a lot under acceleration and Im not sure whether to get z3m or powerflex bush, anyone help?

Your best bet is to convert the car to a twin ear diff mount before the single mount comes off the boot floor.

that is on the list of things to do and good advice.
had welded diff in with powerflex bush and it didnt flex so Ill stick one of them until I can get it sorted properly.
just had gearbox bearings done £475 and noticed the uj on prop is knackered £180 to get that done on top of the new lsd which really hurt the wallet.
a week after I got it one comes up on here for sale for a lot less!!!! sods law eh
