adjusting a clutch...

am i missing something? from my understanding of a hydraulic clutch system, if your clutch is "letting out up high" you CAN NOT "adjust the linkage" by the clutch pedal to totaly fix this.
am i right or wrong. i think i am right. yes you can do *slight* adjustment BUT you CAN NOT adjust THAT much...
thanks for the input.

Can't you just turn the push rod in and out to adjust engage point? Did this on my girlfriend's 93 miata to nice effect. Just have to make sure the switch is also adjusted properly.

Or am I missing a point?

The linkage by the pedal is the only adjustment.
Start by loosening the adjustment pin. Adjust it so that there is just a little play before it starts to press the hydraulic cylinder. Tighten the lock nut. Drive the car to see where the clutch engages. If it is too high, add more play until you get it where you want.

A problem for people with some aftermarket clutches is the pedal engaging too close to the floor. Sometimes
the pedal adjustment won't get you much relief.

Interesting... do the aftermarket clutches begin to disengage at the same point as the stockers? So you have a broader sweep between fully engaged and fully disengaged?

Would'nt you need a ratio change to get back to the stock range? A different fulcrum point on the throwout arm would do it, no?

I think the thicknesses of the pressure plates, flywheels, counterweights, and clutch disks varies a little from one manufacturer to the next. I put in a SR flywheel with an ACT SS clutch. My engagement was lower than I would have liked. I adjusted as far as I could, but it's still just a little low. My preference is to have the engagement a little higher on the throw.

all you have to do is mod that little rod going between the clutch pedal and the master clutch cylinder. there is only so much you can actually screw it in to the welded nut on the clutch pedal so after that, you must actually cut the little rod or grind it down a bit (well theortically you can to give it that extra low setting). I have read the faq everyone else has about adjusting it to the level of the dead pedal but idk if thats really possible with the stock rod seeing as it only screws in to the pedal nut about 3 cm or so (seems like you gotta screw it in at least 2X as much). Let me know if you actually get anywhere. As for buying a new clutch master which has a bigger push, it seems very possible that this will work although you must be careful when you adjust it and not to have it so large as to have the clutch fork grind agains the housing (because it pushs out too much, i have a friend that did a auto to manual swap on another car and he ran in to this problem). This actually can be avoided fairly simply by putting the clutch stop/rubber bump farther up so i doubt it will be very much of a problem.

I think a lot of the aftermarket racing clutches out there release a bit higher. Like my ACT s/s clutch released VERY low at first...but now it releases up high. It grabs hard tho...probably gonna lose a mount or two
