Question for those with clutch experience...

Just got car back yesterday after oil, plugs, RSS mounts, alignment, new coils, tune, exhaust and some other misc PM. Made it all of 30 miles before clutch was slipping. Now need to take it back. The long term plan is maybe better intercoolers and some supporting track mods if I start DE's. No current plans for big turbos or much more power.

So...what clutch options you guys like best. Please keep in mind I just dumped a $h!t ton of money onto this car (see above &#128521 and price matters a little in light of that. I appreciate all opinions here. The shop doing the work has made some good suggestions and done a great job so far. Looking to see what you all think. 👍

Sachs 2.5. I got mine from Mike at AWE. Stock like feel and can handle 750bhp. Worked great in my car on track and street.

+1 for Sachs, it's handling the power on my turbo with an APR tune.

Sachs 2.5, and like it was said talk to mike at AWE.

I would double check the pricing you mentioned, sounds off if comparing part for part.

Sachs 2.5 will handle more power than the GT2 clutch and its the same manufacturer used for the OEM parts if I remember right.

I personally also did the slave conversion and an very happy with it.

Happy to answer any questions.

The Sachs 2.5 is not 3k.

You don't need the LWFW.

Sachs 764 (stge 2.5 whatever..) is def the way to go. Wouldn't touch a GT2 slave conversion or there goes the usability factor out the window....along with your resale. GT2 is a great toy but a DD it is certainly not. The 2.5 will give you a slightly better pedal feel anyway once you get rid of the stock sprung clutch plate. The gt2 conversion is just a money spinner for the shop.

Fresh back from your ban and you're really back at it right away with the same old passive-aggressive rude and condescending banter?

The stock clutch has little feel and inconsistent engagement. The accumulator is a weak part and mine was going at 45K miles.

The shop was replacing my OEM accumulator/slave anyway under warranty (was my last visit before my factory warranty runs out) and I overnighted the GT2 slave conversion parts to them. The only significant extra work they did was the power steering pump modification, plugging of the old assist line, and new spring booster for the clutch pedal. It wasn't anything they brought up and it was entirely my decision to have them do it.

Now that the clutch has broken in I'd say it has 30% more resistance than stock with 200% more feel and consistency. I DD my car and the clutch is perfectly suitable for driving in traffic. Not as light as OEM or my girlfriend's Mini Cooper but as soon as you spend some time with it you get used to the new feel and pushing the clutch is as natural as it was before the mod.

If I was worried about resale I wouldn't have done ANY mods to the car at all. Op just did a bunch of work to his that will not help resale (e.g. RSS engine mounts). But thanks for the tips...

Kudos to EVOMSit for making the GT2 conversion kit and John@SpeedTech for getting me linked up with it.

A bit rich coming from someone I called out for spruiking false information that Michelin's PSS were to be standard equip on 991. And we all know how bent out of shape you got yourself when i called you out over that fanciful claim. You need to start working with facts for once and not go attacking someone who recognised your info was flawed and who called you out accordingly.

In so far as my comments on the slave being hardly a majority fit for the average 997tt user, my statement is fairly called. Having the Sachs clutch myself, and being a Sachs dealer, i also feel i am qualified to make comment on that, and their products. You on the other hand seem hell bent getting even on my calling your nonsense out on those tires. You need to accept that you cant go spruiking nonsense around expecting to get away with it. There are many that use theses forums for quality information, and who may not wish to base purchasing decisions upon wild claims which you have shown to have a tendency of making.

A GT2's assist-less clutch is easily a daily driver.

As far as being a money spinner for a shop, you could say the same about the repair feeding Porsche's pocket when the OEM parts fail.

Not a Sachs dealer. But I did stay at a Holiday Inn Express last night.

Having used the GT2 conversion for 5 years and 70,000 miles, as a daily driver, I totally disagree with this statement. The GT2 conversion enhances the driving experience on a daily basis and does not affect the "useability" of the car whatsoever. I doubt it would have any affect on resale value.

What it does do is add precision to the clutch action and enhanced enjoyment to operation the vehicle. We have sold loads of these kits and I hear the same comments all the time. Everybody that installs the GT2 conversion, whether on a 996TT or a 997TT is extremely pleased with the end result. IMO, it's one of the best modifications you can do to enhance the driving experience.

And here we go again.

Your memory is failing you.

Want to talk about facts?

I never said anything about the 991 coming with Michelin PSS.

I don't know what bearing that has at all on this thread either, even if I did.

I just discussed my real world experience with my 997TT and clutch slave conversion which you seem to have completely ignored, deciding instead to rant about something completely unrelated.

I have no idea WTF you are talking about. You didn't say anything about the clutch slave conversion simply not being a fit for the majority of 997 turbo owners. Moreover, you're responding in a thread to a guy who just did a bunch of things to his car that indicate he's definitely not part of the 'majority' owner club.

You're crazy dude.
