Best slave cylinder for v6

What is the best concentric slave cylinder for the v6?

My 2002 ZT v6 (160) needs a new clutch.

I would appreciate feedback from anyone who has had a clutch/slave cylinder replaced in the last 2 years or so, and weather it has lasted so far, or not.
What make was it? How many miles covered etc. Was the master changed at the same time?

There are sellers out there who one minute recommend the metal slave and advise to avoid the LUK, then months later the same seller recommends the LUK and advises to avoid the metal one and so on and so forth.

Luk or Borg and beck.

What experience do you have of either of these?

The LUK seems to have a high failure rate. I've read more than a few stories of LUK slaves not lasting a year or even failing straight away. I've also just fitted an LUK clutch to my mums Peugeot 207 and the new release bearing is noisy.

I’ve fitted a few luk slaves, and find them to be very reliable if fitted correctly, I have only had one fail prematurely.

That doesn't inspire me with confidence depending on how many you mean by a few. If you've fitted 40 then I guess one failure isn't bad. If you've fitted 10 or less and one failed, then that's not great.
Reliable if fitted correctly - what do you mean exactly? I can't see how they can be fitted not correctly.

LUK Repset Pro fitted correctly will be fine, if a CSC is noisy when fitted, it is generally as a result of incorrect fitting technique, more so than poor manufacture, unless it's a TAZU

I've fitted a mixture of different makes over the past few years, and out of all the LUK slave appears to be the best, the worst of all being the TAZU all metal slave.

The absolute worst of the worst quality clutch plate and cover are manufactured by Transmech, and I wouldn't have one given.

The last clutch I fitted was an XPart three part unit, but I in hindsight I would have been better off with an LUK variant.

It is important to clean out the master cylinder thoroughly prior to connecting it to a new slave, as not to contaminate the new unit.

It's dead easy, just try wangling one into place without removing the gearbox from the car, leaving it dangling on the subframe

Or not cleaning the splines properly.
Or not cleaning and flushing the master cylinder through before connecting it to the slave.
Or or not replacing a worn slave guide.

Then you have the same fitting issues with the pressure plate and driven plate as you would on other make of cars clutch changes..

...so not much really!

Yes I get what you are saying. However poor workmanship can happen on any car so I'm not sure why 75's have a higher failure rate.

Poor quality components with no manufacturer to control this I guess. Parts being in a genuine MGR box doesn't mean anything these days.

Yes, there are a lot of substandard parts around, this was also the case when Rover were trading though, any production item will have a failure rate of some degree.

Fit a reputable make and follow the advice on here, you wont go far wrong
