MPL Clutch Slave Cylinder
Any one else tried out one of these clutch slave cylinders from MPL tuning in Germany?

I had one sent over and after this was fitted (along with new clutch) this made a very noticeable difference and the clutch is now pretty much as light my modern 2009 car, a huge difference. Well worth it if anyones looking to replace. Well engineered piece of kit.

Was looking at softening the clutch and seems like a good thing to do whilst the clutch on mine is being replaced.
Did you do yours recently and was it expensive? Did you source the part directly from the manufacturer?

A few on 911Uk have fitted them, all with universal praise
You can buy direct or through E Bay, where you might get it slightly cheaper
I would be inmterested to see how much difference a new standard slave makes by comparison, they are considerably less money

I had a new standard slave fitted and the feel of the pedal felt the same as it did before it was replaced (clutch wasn't changed at the same time). The pedal feels a little lighter since having a new clutch but it's only marginal.

Thanks Steve, so no point in that move, unless the existing one is failing/leaking

Yeah over the standard slave cylinder and this mpl there is a noticeable difference, i think the internals are slightly different design.
Even the garage (unit 11) that fitted this for me were suprised and asked for the supplier info and they have done their fair share of replacements. I managed to haggle to £140 inc shipping as i referred to the ebay history going from anywhere between £90 and £160. Well worth considering if your having a clutch done!
You are going to pay more over the porsche standard new slave but well worth it given the difference.

The MPL unit claims an approximate 30% reduction in pedal force. The only way to achieve that is by changing the piston diameter, which they admit to doing in their on-line brochure. As a result, clutch slave cylinder rod travel will effectively be reduced.
Along with a new clutch hydraulic hose and a complete pedal assembly rebuild (cleaning, new pedal bushings and re-greasing), clutch action is whisper quiet and ultra smooth.
An update to those observations: that is how the clutch actuation system felt just after finishing the installation and while still parked in the garage waiting for winter to come to an end. Shortly after getting back on the road, the the much-talked-about-on-Rennlist "grawk" initiated again and has not gone away; it is sporatic. I can only assume the issue is the original and old pressure plate and/or the release bearing actuator fork.
Brake fluid used was ATE Super Blue and flushing/bleeding was performed with the aid of a Motive Products Power Bleeder, both sourced from Pelican Parts. I modified my Power Bleeder to make using it in the "dry method" easier.
Not a DIY set of instructions, but plenty of pics with some tips. This is for a 993; I don't know how similar it would be to a 964.
