alright im chiming in again...for you guys with the Exedy twin HD or not when you down shift whether or not you rev match (or heel-toe if you so choose) do you hear a squeal/screech from your clutch as it engages say from 3rd to 2nd? It doesnt happen all the time only when im trying to be smooth about a down shift im assuming its doing that because engagement is taking longer...also how much chatter do you notice?

 

ya that happens...its normal from my understanding....the slower you let it out the louder and longer, right?

 

I've not got that sound out of mine yet.. I do get lots of chatter when i've got the clutch down and I'm coming to a hault. Also at idle there is lots of chatter with the clutch down. It seems that when the tranny gets warm.. the chatter lessens but is still there.

 

I only hear the squeal if I don't rev-match. No noise at all when I rev match it.

DRIVE IT!!! It will either break or hold, it's a racing clutch.

 

exactly.

 

Has anyone had to use the clutch release rod like the one on lancershop.com to allow the clutch to full disengage??

 

???

You can easily get the clutch to fully disengage. The buest way to get the clutch adjusted properly is to put the car up on jacks(all 4 wheels off the ground), and let the clutch out SLOWLY you want the wheels to start spinning after about an inch of release. Adjust the rod to allow this. You'll have to do it a few times as the clutch is breaking in. I found that after i did this it drives perfectly.

Maybe someone with more expertise on clutches can verify this for me but it seems like the clamping force is applied exponentially as you release the pedal with a twin disc, whereas with a single disc its more of a consistant increase in pressure. Is this accurate?

 

From an engineering standpoint, you can sprinkle pixie dust and snake oil and say a few magic words over it... it will do the same thing. Actually the oil may help a bit more because of the lubrication.

 

I think the grabbiness(hehe I made that up) is because of the removal of the restrictor pill. I still have mine in. Love it!
EXEDY FTW!

 

TRE recommends 3 inches off the floor board.

I tried that but engagement just seemed way to high for it. is it supposed to be 3 inches even with a twin disc?

 

hehehe.. you mean there is a right and a wrong setting for the clutch pedal? After I got my Exedy Twin HD put in i've been messing with it off and on adjusting it to whatever "felt" more like the stock pedal. I guess I better do the jack-stand thing. Good thing I've only put like 300 miles on the clutch since it's been installed.

 

Here's the original quote from John @ TRE:

Judging from that I'd assume that means any clutch, since I can't see anyone trying to shift the stocker that high... Although 3 inches off the floor is probably something like 2" of travel, since the pedal sits about an inch off the floor when you press it all the way in.

I believe, not sure, but I believe, he's talking about if the car is on the ground. I could be completely wrong and he is the expert not me. Also hes mentioning doing that to get it to shift above 10,000 rpms which requires more clearance from the flywheel. All I KNOW is that this is how I set up MY car and it works great for ME. Now, how that might work for someone else, or someone elses car may not be the same. I also haven't brought my car over 8000 rpms(2.3). In any case, to the OP, try that and see how you like it.
