The clutch on my 325d has started to slip so I want to take the opportunity to upgrade my clutch to something that will cope with the 635nm more, oem clutch is on 85k (45k with the map) so the oem clutch can handle the power but want something that will last longer.

Can't find any performance clutches for the 325/330d N57, what are my options? Realoem list 3 part numbers for my clutch which doesn't help either.

Thanks.

ive a standard clutch with 120k miles and mine is ok,,i have 698 nm,,mind you i dont drive it like a tool all the time..just get luk clutch and dmf and it will be fine..

Try this place - http://www.clutchstop.co.uk/330-d-1/

I bought my DMF from them but they stock performance clutch plates too, I'll be getting one next time round.

Hope that helps

Thanks for the replies you two, I'm currently away so there is no rush for me to fix my car as it's not being used.

Shall I go for the Sachs performance clutch and pressure plate rated for 540nm

Or the NRC clutch and pressure plate rated for 570nm?

Thinking of going with the Sachs as it's a well known brand and don't want to spend £600 plus labour to find the NRC clutch can't handle It, however the seller CCC automotive seem to have a good reputation.

[cvincent3]

Scrap that, CCC automotive don't have good reviews on their Facebook page..

[rasa bmw]

570 nm doesnt seem much.although thats probably well inside what they can really handle.just like the standard clutch which can handle mapping to 700 nm,im talking 330d here though

[cvincent3]

Doesn't matter if you're talking 330d aslong as it's the N57 engine as that's the same engine in my e92, aren't talking about the M57 197 bhp engine.

That is what I was thinking, the torque claims are going to be a lot lower than what they can really handle, but just want to hear someone say they have either the Sachs performance clutch or the NRC clutch which comes with the Sachs performance pressure plate, the NRC is cheaper and claims higher torque rating, but realistically it could be horrendous, whether it's to cope with on a daily drive or can't cope with 570nm at all.

no m57 ...but i assume the n57 will have the same or more torque handling abilitiy,after all it has another 10 bhp

It does, when I was looking up the part numbers prior to doing the clutch and DMF, it was obvious that the pre-LCI DMF and clutch were lesser rated parts.... I think the pre-LCI DMF is a good 1-2kg lighter than the LCI (N57) version though I'm not sure how different the clutch is....

[cvincent3]

So I went for the Sachs performance clutch and pressure plate from Clutch stop and my mechanic messaged me today saying the car has a horrible vibration on idle and take off of drive.

Clutch stop aren't being very helpful so I think I'm going to have to pay my mechanic twice to remove the Sachs and fit a LUK standard clutch and try and get a refund from Clutch stop as the clutch kit isn't very good at all.

that performance clutch,,was it a single dmf..if so then that will be the issue.

What do you mean by "single dmf" ?

[cvincent3]

It was designed for a dual mass flywheel if that's what you mean? Not a single mass.

so you didnt change the flywheel when replacing the clutch? is so the company will ahve a good argument as to that being the problem of vibration,,,dont think ive ever had a new clutch with doing flywheel also.

The flywheel was inspected by my mechanic and said it was absolutely fine, has done 80k miles.

If the flywheel showed signs of wear before the clutch replacement and being inspected during the clutch change then I'd of changed it, however it's in good condition.

80K is a fair bit of wear on a DMF, I changed mine recently at 110K but that was the second DMF the car has had. I had to do the clutch anyway as mapping it highlighted how worn it was. Before the change the car would judder when engaging 1st gear unless you gave it a few more revs...

Changing both whilst also having the gearbox oil changed transformed the gearchange and general feel when engaging gears, much more direct and smooth whereas it was a bit "soft" by comparison before. And no more juddering of course!

[cvincent3]

Think I'll change the flywheel in that case. Always worth getting another opinion.

Thanks guys.

it makes sense,,i know the flywheels for these cars are not cheap(luk) but neither is labour..and paying out twice aint fun.

[cvincent3]

Fingers crossed that the new flywheel solves my vibration issue, only thing I can think of is that the extra pressure from the Sachs performance pressure plate has caused extra strain and caused the vibration on my old flywheel which wasn't noticeable before with oem clutch and pressure plate.

Got a LUK flywheel for £517 from GSF using their discount code which is the cheapest I've found it.

This was my initial thought, with the new pressure plate having so much more bite than the worn one you've taken out, it would have highlighted a worn DMF too.

Hope the new flywheel sorts it for ya

Thanks Sirleeofroy, I'll report back in a weeks time when the flywheel is fitted. Hate searching for problems to find thread un answered incase anyone has the same issue and doesn't want to replace their dmf after a clutch change 🙄
