DKM twin clutch (organic)

Quaalu said:

The pedal was noticeably stiffer with an inconsistent feel throughout, but it was easy to get used to and now it feels smooth like stock. I occasionally drive a '64 Mustang around town and I can say I'm cool with any clutch lighter than one that requires the knee cap mod down the road.

I get the feeling there aren't too many on these forums that have experienced a real, heavy, classic muscle car clutch.




Is the bleeder valve in the picture I posted originally? How can I get more fluid to help the initial engagement and will this compromise the clutch's ability to hold torque?

The engagement in first is definitely starting to smooth out as I go easy on it. I've done nothing but painfully slow engagement for a couple days (only off the line into first, normal engagement for all other gears). Now a normal engagement into first feels significantly better than I explained before. Will continue and provide another update later.

The clutch hydraulics have no play in its ability to hold torque, that's the pressure plates job. The bleeder block flowing more fluid improves clutch feel by allowing your input at the pedal to directly transfer to the clutch. Stock it has a delay valve so even if you side step the clutch it meters the fluid and only allows it to slowly release (slowly being fractions of a second, but slower than the pedal movement to the point of being notable)

As for heavy clutches, I've personally driven a few 60s Mopars with a heavier than pleasant clutch.

If you really want a leg workout drive a diesel truck with a performance clutch. My Cummins had a 3400# pressure plate

You shouldn't be using that much throttle at low rpm, it's really hard on engine internals. But anyway congrats on the car and welcome to the forum.

My clutch slips too but I'm just gonna drive around it (drop more gears before getting into boost) till mines actually worn since I plan on keeping the car past 200,000 miles and don't wanna do multiple clutch changes.

So how is the revs now that you are rocking the SMF w/this clutch kit? Chatter? I think this will be my next clutch.

Thanks for keeping us updated on this clutch Quaalu

Damn, what a beautifully made clutch!


Jake, I find it quite odd driving a car I can't put the foot down with.

Yeah ok it's hard not to some times. It's helping to break me of driving it like a diesel tho and that's a good thing. I've spent a few hundred thousand miles driving my Cummins and Tdi and loved the torque

Now approaching about 2k miles on the clutch and there is hardly any chatter felt after re-bleeding the clutch a few times. You can hear it slightly when in neutral. You can also feel it chatter when you engage into first under 1300 rpms. At 1500+ rpms engagement is smooth.

Glad to say this is the result I was looking for and can officially recommended this to those of you looking to upgrade.

Thinking about removing the other delay valve in the clutch line located near the firewall. Added APR shifter bracket, APR short shifter, and 42 draft designs shifter bushings - which didn't fit within the length of the metal pins on the shifter. Overall I love this clutch and would choose it again.
