I have about 200 miles on my DKM, so I'm still breaking it in. When I first stepped on the clutch pedal, I thought "oh no, what did I do." First 100 miles were pretty heavy, but the clutch is easing up some. Still very noticeably heavier than stock, but we'll see how it feels after break in.
While it seems the TOB issue has been cleared up with DKM, through my own opinion and my mechanic's recommendation, I used the metal Mk6 TOB. A full metal, single piece TOB just seems to be one less possible point of failure. I also had the fluidampr installed at the same time. Like other people are reporting, very little chatter, and has decreased even more as I progress through break in miles. Clutch grabs and overall I'm very happy with this clutch especially if the pedal continues to get a little lighter.
Also, filled with Motul gear 300. So far, it seems the tranny is happy with it.
I have two small complaints about the clutch. The first is, the clutch judders from a stop. It's strange, if I'm rolling forward at all, even 1/10mph, there's no judder and it's smooth. I've seen other people on here report similar issues and recommend being a little more aggressive on clutch engagement, so I'm hoping I just need to learn this clutch.
The second is, the twin disk generates a lot more cabin noise. Granted, I had engine/tranny/dogbone mounts along with an exhaust installed at the same time. So, it's tough, if not impossible, to pinpoint whether the clutch is significantly louder or a combination of that with more NVH through the mounts. It's not loud enough to be an issue with the radio on, but the "luxuriousness" of the golf interior has declined. Again, not a big issue, but noticeable.
