Wanted - LSD to fit a E36 328i

you're more likely to find the 3.0 M3 (3.15) LSD than the 328i Sport's (2.93) LSD TBH (These are hens teeth rare these days!)
Be aware also that you can get a 328i one from an early auto Sport and these will be a 3.07 ratio which is a nice 'halfway house' between a 325/M3 3litre and a 328i Manual SportDoes anyone know about Carbonetic LSD's or had experience with one:

the M3 LSD's are pretty easy to come across
expect to pay around £300
by fitting the M3 LSD you will get quicker acceleration but you will lose a bit of top end and the mpg will be slightly affected
if you can, try to get a hold of the full M3 propshaft by doing this it will save you the hassle of changing the input flange on the LSD which can potentially mess up the preload setting on the nosecone bearings and destroying the LSD
another thing to do is to remove the rear and side covers and remove the clutch pack
there are 8 aleen headed bolts holding the back plate on the clutch pack
these bolts have a habit of rattling loose and try to pick a fight with the crown wheel and ring gear
make sure they are tightened up and add a dap of loctite too

They seem to have a very good review from people using them in other cars, quick search on google brought up people using them in 350'z and big power cars, said they bettered other types of diff theyd experienced. Good price too...
Sound good - what are the fitting costs?Part of the appeal for the OE ones is that I was able to swap the whole diff over myself ( with a pair of helping hands to steady it on the jack ) in a few hours meaning I wasn't without the car plus I have the old open diff to switch back to if there was a problem. If fitting costs are low for something like the Carbonetics one it would be a worthwhile swap though
I was quite lucky in that the ones I've fitted hadn't been 'cooked' by hardcore drifters so still seemed to lock up acceptably enough but I take the point about many 2nd Hand ones being tired. Maybe an autobox car was a good choice in that it didn't attract so much shenanigans

Worth thinking about - If your 328i has traction control, you can just remove the throttle butterfly in the traction control throttle body. This causes only the 1st stage of the tc to work (it works in 2 stages, 1: brake the spinning wheel, 2:cut the power)
This means that the spinning wheel has the brake applied to it, causing power to be diverted to the outside wheel...this causes it to sit sideways very nicely, makes for superb progress and is massive fun, its effectively an e-lsd. I've decided not to bother with an lsd in my 328 sport since finding out this, although I probably wouldnt want to do a full on drift day in it.

You'll find the braking effect only works really well below about 30 - from 30-60 the braking effect is reduced - over 60 it won't pulse the rear brakes at all ( to avoid them over-heating ) - only the throttle body works at speeds over 60.

If it suits your needs though, go for it!

Spot on, I've found above 40/50 the car can be made to slide pretty well (if thats your thing) - just from weight transfer and the cars natural balance...so (for me, at least) it renders a proper LSD pointless - on the 328i at least, its got such great traction (/not enough power) to really make use of it at higher speeds (unless you're into full on drifting for the sake of it, even then, like i say...weight transfer is your friend)If it suits your needs though, go for it!
