yes so i just shot you a PM actually. I have sitting in my house the SRE performance pressure plate. https://www.fcpeuro.com/products/pressure-plate-sachs-performance-883082001422#reviews

id like to use this with the stock friction disc, but im not sure if it will be compatible, and getting information from "Benny" at sachs is like pulling teeth. The reason id like to use the stock friction plate over even the organic full face plate from sachs, is the OE plate is sprung, so should be smoother.

Benny stated the stock friction plate wouldnt fit with the SRE performance pressure plate, but when i asked for a reason, he wouldn't tell me why. Also in other forums, it seems like there is parts compatibility. I want to be sure though before i spend a ton of money that it will work with the factory friction plate, and Benny is just giving out wrong information, or trying to sell me.

I replied to your PM. The short story for this thread is that I don't know the answer as I'm not a clutch expert. I would be nice to be able to use the SRE PP, but if you're in there, you might as well put in the full face friction plate. :)

I had the SRE pressure plate with a stock disc and eventually it started to slip. Doesn't make sense to beef up the pressure plate and leave the stock disc being the weakest link.

Have you driven in a car with a full SRE setup? I have the full face organic disc now and it's not much different than before. Only difference is it holds the increased torque with ease.

Whatever you do, do it right from the beginning. I've had my trans out 3x in the span of less than 20,000 km, it's not a fun experience and isn't cheap.

I ended up returning the Sachs PP to FCP euro, and ordering a TTRS PP. the kit on DAP uses a stock friction disc and it seems to hold up.

I wasn’t willing to be the lab rat on the Sachs and stock friction disc. Sounds like I made the right move based of your message.

My main reason not buying the Sachs friction disc is I’d like to maintain a sprung disc

Yea, having a sprung disc definitely makes engagement smoother.. It makes everything smoother.

I just purchased a sachs 4 puck and a sachs pressure plate with a new dmf to replace a failed bfi stage 3 clutch (failed after 30k running e30 stage 2 and then a vortex xl @29psi 91 file.) I'll let you know how it runs after I install it and it's broken in.

2018 GTI Autobahn 6sp M/T.
Looking at upgrading clutch. Pushing 360HP. Clutch is slipping BAD when downshifting from 6th to 5th , or 4th. Also slips if I get on it hard when in 4th, 5th or 6th.
no issues in the lower gears.
Was hoping to keep the DMF as it only has 18K on it.
Daily driver to and from the VA.

Any help would be appreciated.

For a daily driver, I think I would have to recommend the full face version of this clutch. The 4 puck unsprung clutch really takes away from the refinement of our cars. If you want an all out race car, then the 4 puck is pretty good.

I just installed the fourth clutch in my 2015 GTI.

First, the stock clutch. The stock dual-mass flywheel used rubber springs. After I went to Eurodyne Stage 2, these turned to goo (due to heat from clutch slipping because of increased torque?).

The second clutch was Sachs's 530Nm clutch (https://www.sachsperformance.com/en...h-sachs/performance-clutch-kit-001422-999505b) with single-mass flywheel and sprung plate.

There was some chatter ("is something wrong with your car?") and the clutch pedal was much stiffer. It lasted about 45,000 miles, including about 15,000 miles on an IS38 tune.

I made the mistake of replacing it with another 530Nm clutch. At this point I also installed a Wavetrac LSD (which may have increased the strain on the clutch by maximizing torque to the non-slipping tire?). The clutch lasted about 15,000 miles on IS38 tune, again.

So now I've gone up to Sachs's 810Nm DMF clutch (https://www.sachsperformance.com/en...h-sachs/performance-clutch-kit-001422-999505b) and their DMF (https://www.sachsperformance.com/en/clutch-kit/zf-sachs/flywheel-vw-golf-7-gti-169kw), which has metal springs instead of the stock rubber, so that failure point is eliminated. (Incorrect information; see @ZuMBLe post on next page.)

My initial impression is that the pedal is much softer (stock-soft), which surprised me, but the engagment is much more aggressive, which did not. I'll give further impressions in a few thousand miles.

Link to the DMF you installed?

Thanks for the great info! For the Sachs DM flywheel, is this the one you got? Sachs site lists it as OE implying stock VW, but FCP Euro site says it is OEM. I'd like to avoid rubber springs if I can...

Edit: NVM, I'm too pokey - in the time it took me to post my question, someone else already asked and you answered, lol

@dunkelweizen That's the one.

And you know… I looked at the picture and thought "metal springs," but now it occurs to me that that might be a stock picture.

I should have called Sachs to confirm. :unsure:

I saw the picture and also wondered if that was just a generic stock picture/diagram.

I just sent Sachs a message through their website asking to confirm whether it is metal or rubber springs inside. I'll update when/if they get back to me.

Cheers.
