The adjustment is at the pedal assembly. There is an adjustable rod that connects from the pedal assembly to the master cylinder and actuallly pushed directly on the piston of the master cylinder. Normally there is freeplay before the rod makes contact with the piston. Adjusting to have less freeplay will raise the clutch engagment point and allow more disengagment at the floor since the piston of the master cylinder is traveling farther. Increasing freeplay on the rod will lower the engagement point and reduce m/c piston travel.

 

Ok, after 800 miles of breaking in, normal driving, I spent the last 100 miles driving it like I usually drive, bit harder than normal driving.

The clutch engagment feels a lot like the stock clutch and the shifter shifts into the gears a lot crispier than before (it was smooth before) and engagement is so immediate, I love it.

However after not having any problems with vibration and chattering, I'm having that now at 900 miles into the new ACT clutch.

I could feel the vibration on the clutch pedal as well as the dead pedal. I know this isn't normal or is it?

I don't think from all the threads on this topic, we've never resolved it and gotten a straight answer why this is happening to some cars and some don't.

I know it usually goes away for some, but I just want to make sure.

 

Thanks Dirk for the reply. I figured that the adjustment should be at the pedal and people are not adjusting their clutch engagement points so they smell the clutch burn a little.

Also what kind of Flywheels are you guys using?
Stock or L/W aftermarket?
Also what would be better to use?

 

Dirk, so should we be adjusting pedal free play to factory specs with the ACT clutch set? If not, what do you suggest?

 

So here's a simple question, mine is a little on the high side as far as pedal/engagement goes. If we want to bring the engagement closer to the floor should we move the adjustment bolt towards the firewall or back? I haven't looked at the assembly in a while so I'm having trouble visualizing it all. I have noticed my engagement point rising a bit in the past 3 months with daily driving only. I feel I should readjust it because when I'm going up hills slowly in traffic or parking lots it is a real pain to manipulate lately.

 

Honestly, I am not sure how Mitsu describes the "factory spec" and I have seen many factory cars vary on the original adjustment. The two important factors are? full disengagment (pedal engagment not adjusted too low) and no preload on the master cylinder (adjustment too high). The rest is really just preference.

 

Screwing the rod toward the firewall will raise the engagment point since you are making the rod contact the master cylinder's piston earlier. If you want to lower the engagment, screw the rod away from the firewall. If shifting suffers, you have gone too far. I have noticed that the stock release/engagement point seems a bit high but is needed to get full disengagement.

 

ACTman - Off topic, sorry... but do you know when the release of the ACT Xtreme will be for the EVO 8 GSR? I was about to order a Heavy Duty from ProStreetOnline.com but am debating on waiting for the XTreme.

Thanks!

 

one of my friends got that and didnt like it at all. keep us posted

 

Thank you for the explanation Dirk, I readjusted mine the other day and boy does the clutch feel better

 

We currently don't have plans for an Xtreme pressure plate but I am sure that will change as the need for something more than our HD increases. We have a lot of other development in the works that may influence our product offerings for the EVO in the future.

 

Cool. That's what I like to hear! Glad to help.

 

Great information Dirk!

 

The owner's manual (PN MSSP006C03) page 7-24 gives the pedal free play spec as .1 to .5 inches (4 to 13 mm).As indicated by spec.s there is 9mm to play with should someone desire to customize the pedal. Mine is 1/8 in. with your clutch set installed, the restrictor disk removed and the system properly bled. The pedal feels perfect to me as does the clutch. That is to say, it engages and disengages right were I anticipate it doing so. Dirk you can tell your boys they make a great product. Alex, I received my clutch set on the Monday folowing the Thursday I phone oreded it. Great work we will do bus. again. Oh and the price was the best as well. $476.99.

 

Yeah Dirk and the crew at ACT were the only ones that came to mind when my stocker was on dying on me
