Lsd Options?

Recommended Posts

As per title, what options are there for the 330ci, i know all about the M3 diff and theres the quaife ATB diff available, but who else makes/supplies lsd for our cars?

i will be wanting to get one fitted in the near future in my 3.38 diff!

1. Call bank manager

2. Get Quaife.

You can put in a M3 diff but you have to change driveline and axles and stuff too.

i've had a few emails regarding a gripper LSD, they are looking to do some work on the fitment for ours so will just wait and see how successful they are!

Kaaz do one. But bear in mind that a mechanical LSD like the M3 is, is imo much better than a helical one like the quaife. Think you have to service the quiafe every 20k or so as well.

M3 whole rear axle, and adapt the prop shaft. Thats what i would do!

You know a helical gear is still mechanical right?

just a point about HELICAL gears... I use them in my helicopters....A helical gear gives you 2 contact points on the APEX of the mesh and are a lot less NOISE generating than strait cut gear meshes...A helical gear will allow more power through the train before catostrophic destruction from overpower ..the downside of a helical gear is it pulls to one direction as it loads up so wears out bearings on the loaded side really fast...

I obviously is still mechanical, but works differently to the M3 one. TBH you would never really tell whilist driving, well unless you were powering into every corner etc

But I still personally think the M3 one is harder wearing, and a better design for everyday use.

If it was a track toy only, and you were ok able to service it every year, then the quaife would be fine. Well I'm sure the quaife would be fine anyway, but I know a few people admitadly in the VW world who have had to get theirs rebuilt, and more than once in a few.

I used to run a Kaaz 2 way in my drift car and we used to change the oil after every other drift day or 1k miles, whichever came sooner. Normal Helicals, you should get away with doing it every year at least. And Helicals are a lot lot quieter than a Mech diff. Like, you'd never know it was any thing different to the Open diff til you put your foot down. Quaife ATB is my vote.

The Quaife is very hard wearing. It has a lifetime guarantee. It works differently to the M-Diff and mechanically is constantly transferring power to whichever wheel has the most grip. My brother has a quaife and it's a fantastic piece of kit. I prefer the way it feels to teh M-Diffs I've had on the E36/E46/M Coupe.

I would certainly go for a Quaife if I were in your shoes.

I've been waiting to see if they can develop the gripper LSD for our cars and so far they have done the 330D LSD and are currently working on the 330ci fitment apparently, if not i think i will be going down the quaife ATB diff route!

I've been talking to neil at automac and they have been developing them for the e46, he did say they had finished off the 330d lsd and was ready to fit/test iirc, and was about to start on the 330ci lsd, this was mid november last time i emailed him,

Gripper have been making plate LSD's for a while now, i've driven a few fwd cars with them but not experienced a rwd with one as yet, i'm not in a mad rush as i don't drive the car that much with having the works van and winters here so not to worried!

Hmmmmmmm.. Not cheaper by much then! A gripper is £850 (exc. VAT and delivery) from them whereas the Quaife from Birds is £830 exc. VAT and delivery..

Depending on what day you ask them!!! They quoted me a different price every time!!!! Also I think the price for the quaife is just for the parts & the gripper is fitted into your diff casing??

Don't agree at all Quaife atb LSD is top draw I think personally much better the the m3 oem LSD. I suppose it's down to personal opinion really. You'd be crazy to replace a modify the driveshaft with the m3 setup. Go Quaife it will slot straight no messing about.

Do forget the installation into the casing cost and fitting. :) I'd say add £150

But even just down to cost, the M3 setup would be cheaper, plus you get bigger rear brakes of you get the whole rear subframe.

I've never had a quaife, so perhaps I'm not the best to give accurate opinions, but there's reasons why I have never had one ;.) well as I said on my previous post. I know a few people who have had them in track preped vw golfs, and have them fail, and as they were not serviced to quaifes schedule, they did nothing.

But again, if it was one or nothing, I would still do it ;.)
