Group Buy: MPL Clutch Slave Cylinder

[scaramanga]

As per Rob's original post (here), just wondering if anyone else is interested in a group buy for the MPL Tuning clutch slave cylinder.

I've been inspired by Rob's review of the product which helps to make the clutch feel lighter than standard, so makes for a more comfortable drive.

Product info here: Link to MPL product flyer

I will check the exact pricing tomorrow but it is likely to be in te region of £160-175 (need to check if VAT is payable on top). Please note that this is for the part only, fitting would on top.

Anyway, if anyone is interested, pls reply to this thread so we can figure out approximate numbers.

Yep - interested.

Ok. Unless any others interested, it looks like we have two...

More of a couple buy than a group buy but price would be around EUR150 all inclusive.

Could try to get down further if there is any more interest.

me too !

Looking to order next wk so pls pm me if interested.
Thx

I'm with you on this one Maurice. I don't have any issue with the weight of the clutch pedal and can't see what other benefits this brings over the Porsche part at a quarter of the price.

Does look nice though, shame it's hidden unberneath a bit of plywood []

Ahh, but Clyde that part mentioned is the slave cylinder, fitted on the gear box bell housing ,so with a few mirrors fitted to the underside and a torch you will be able to see it from the drivers seat!

 

[clyde]

You mean you don't have a bit of plywood over your engine/gearbox colt? []

I really must start reading posts properly []

I agree it is expensive, but the change in feel is quite dramatic, lighter and more progressive. I didn't have a problem with the clutch feel before, but thought I'd try it as it was recommended by Ash at Braunton garage as a good upgrade, and I like the result. Having said that it does take a bit of getting used to as it does change the driving feel of the car at slow speeds, so perhaps best to try a car with one fitted first if you are in doubt.

 

[nfearn]

I'll post about it once it's been fitted. My main problem with the current clutch feel is that it's not especially easy to "dial-in" the appropriate amount of clutch release, but that may be a result of something specific to my car such as slightly rusty i/p shaft splines. Time will tell.

As with all of these modifications, upgrades and enhancements, it's a matter of personal preferences. I'm not sold on big wheels and lowered suspension, but if someone wants that for their car then that's their prerogative. I wouldn't post here stating that they're complete fools for doing it though.

They arrived yesterday, look very well made but i'm not an expert. Looking forward to having it installed and (like Nick above) will post a review once fitted.

Just to update anyone who was interested. I finally had the slave cylinder fitted and it is FANTASTIC!

Clutch action is 35-40% lighter, I'm seriously impressed and would highly recommend!

G'day folks,
I'm new to the forum, and Porsche ownership.
I have read this thread with interest and am looking for a bit of advice on the clutch issue. I have purchased a 993 C2 and am delighted with it, the only snag that I have was spotted on the test drive and I have not fully investigated yet.
The clutch works fine, pedal weight is not an issue for me, but when the car is fully warmed up the clutch pedal does not always fully release, and can stay just above the bite point for sometime. It happens more frequently on slower release such as in traffic but will also do it occaisionally when pressing on too. It will eventually just spring back to the 'normal' home position with a gentle clunk from the pedal. There is no evidence that the clutch itself is not operating properly as drive is taken up normally.
Have any of you heard of this and got a suggestion as to where I should start to look???
Appreciate any experiences that you can share - on thread topic of course!
Tony

I had the same problem on my 993 C4 (exactly the same symptoms - worse in heavy traffic and when warmed up) - the problem was solved by Northway's cleaning/adjusting the pedal rather than any of the hydraulics.

Have a look at this article as it may help

http://www.pcarworkshop.com/index.php/993_-_Clutch_Pedal_Service_and_hanging_problem

Not sure exactly what Northway's did but it cured the problem. However Ray (Northway) did say that if that hadn't cured the problem the next step would have been a slave cylinder change.

So I'd try the cleaning/adjusting first.

Hope the above helps.

Kind regards
Anton

I had the same symptoms and first cleaned and greased the clutch pedal mechanism then replaced the kinematic lever on the pedal but neither fixed the problem. In the end I had both the master and slave cylinders replaced (I figured while it was in they might as well do both to save me having to go back when it was discovered that it was the one that they didn't replace that was at fault). That solved the problem.

Cleaning and greasing everything is easy enough and replacing the kinematic lever is no hardship, just a little awkward to get into the depths of the footwell. I would give this a go before replacing the cylinder(s) as the Pcar site suggests that this normally cures the issue.

Guy's,
Many thanks for your suggestions, fingers crossed it is early on the list of potential fixes. I will update you after a dabble at the easier options over the weekend
Cheers. Tony

Tony,

A lot of owners, including me, have had this and I'd definitely start with the greasing as the cheap and easy route. Unfortunately in my case it didn't work, but replacing the slave cylinder fixed it immediately, so that might be your next step.

Cheers/John

I been wondering, is it really 35-40% lighter just because its brand new and people only have their old worn original porsche slave cylinder they replaced it with for comparison? Much like my car runs better after a service, cos I replaced old bits with new bits, ie it only runs better cos they are new, not because they are better.
Or is this replacement slave cylinder x% lighter cos it uses a smaller piston, so you would then end up with more clutch pedal travel, which is not something I would really want

Guy's,
Many thanks for the suggestions around the 'hanging' clutch problem. I took the easy option of a liberal spray of duck oil around the pedal base to see if it made any difference before a more thorough deep dive into the footwell with grease and stuff. Sufice to say, it made a great improvement, almost totally cured as it only 'hung' a little bit a couple of times on a spirited drive of 70+ miles into the deepest South Hams. Lots of twisty roads and therefore lots of clutch exercise. And loads of fun too.
Thanks again
Tony

I haven't actually got around to fitting mine yet but, looking at the design of it, it has an offset inbuilt in the sense that the face of the cylinder where it mates to the transmission is not perpendicular (at a right angle) to the direction of travel of the piston. I believe the original Porsche one is designed such that it is.

If I understand the logic of building in this offset, this means that the Porsche one is pushing the clutch release lever at an angle which is offset by 10 degrees or so from the direction that the piston travels in. While not preventing it from operating (of course), this certainly induces some side-thrust into the piston which will make operation that much harder. The design of the replacement eliminates this.

I'll report back when I've finally fitted mine.
