So I'm getting some clutch slippage under tuned boost. Holds power if I put the tune on Map0 (its a Procede)
For people who don't know heres how you test a knackered clutch:
- Put the car in top gear (6th)
- Get on a smooth straight road and cruise at 2000rpm
- Go WOT and keep an eye on the revs
If the revs rise faster than the car accelerates you have slippage.
Here's some background:
- I am only on stock turbos and don't plan on going big single or hybrids. So don't need a clutch that will hold big power
- This is a road car so I don't want to deal with chatter or a grabby/difficult clutch
- I'm on a budget and will do all the work myself (as always). I do everything on my car and while I haven't dropped a transmission before, it doesn't scare me at all.
- Not in a huge rush as the slip is pretty minor and can just drive with the tune turned off.
- Want to keep any individual purchase below $1K AUD to avoid customs
- Want to keep the downtime of my car to minimal or zero. Ideally i'll just do the job on the weekend.
Based on the above criteria I am thinking of a new LUK dual mass paired with a 550i clutch:

Might not get the clutch from ECS tuning as their shipping costs are usually terrible. Happy to source the components individually.
Anyone sourced a clutch recently in Australia? Would be keen to know alternatives or if someone has priced up a kit cheaper than the links above, keeping in mind of the dot points I outlined above.
Also I think I need new bolts for the transmission housing and a clutch alignment tool, can anyone comment on anything else I'll need?
Long shot, but has anyone had experiences with resurfacing a dual mass? From what I've read its quite tricky and very few places can do it. Also not keen on taking apart the car and finding out it can't be resurfaced. Even if it can, that's more downtime for the car.
Heres the list of required parts:
QTY PART NUMBER DESCRIPTION
1 21207542984 Dual mass flywheel (LUK part number DMF112)
1 21207603248 550i clutch kit (includes clutch, pressure plate, release bearing and pressure plate bolts)
5 23001222894 Steel bell housing bolts
8 11227520706 Flywheel bolts T60 M12x1.5mm
1 83300495449 N54 Clutch alignment tool
2 18307553603 Downpipe->exhaust gaskets (needed as midsection needs to be removed)
2 18307561670 Midsection->axleback exhaust bolts (buy these if yours strip)
Also will be useful to have a flywheel locking tool. Genuine part number is for the lock tool is 119260 but the ISTA documentation says you have to manually elongate the hole. I will just grind my own tool out of some steel I have.
