    Where does everyone's clutch engage? Mine seems to be too far out, it holds just fine, but the engagement seems to be too far from the floor. I didn't seem to care until I started driving my e30 around and remembered how nice it is to have the clutch engage right away. I installed a new clutch last summer and i'm just wondering now if I did something wrong or if it just is what it is. The car is an 02 wrx with an exedy stage 1 disc. Any Ideas? Once again thanks for the input.

    My 02 is the same way. When compared to my Evo, the clutch engages way higher. I don't think it's a problem. I think that is how they are.

    Grrr...everytime I get in the subie right after driving the BMW I feel like a mongoloid who has never seen a clutch before.

    Well then mine seem pretty much normal then. Any one consider disabling the neutral safety switch and puting in a clutch pedal stop of some type, or is that a horrible Idea?

    That's pretty much what I was thinking of, dow do you trigger the safety switch without the pedal going to the floor?

    The starter interlock switch? It's in the install instructions from first post of the second link in my post above:

    The cruise safety switch is separate iirc. So it disengages the cruise as soon as the clutch is depressed (not at the same point as it needs to be to start the car).

    i can tell you that a simple braided line took care of my personal clutch issues. the stock wrx engagement sucked horribly, it was never consistent. Now I know where it's at and never grind gears.

    Thanks for the links, that looks like something I'll be getting pretty quick. Scuba, I've got a pretty good feel for the engagement point, so no grinding gears. My issue tends to be too much throttle too soon on the one-two shift causing mad clutch slip and stinkage, but only if my footwork is lacking during some "spirited driving".

    Mine engages right at the end of the pedal travel. Part of it might be mismatched master and slave cylinders. Anyways, I don't see what the problem is with "useless" pedal travel. I'd rather not have to fully extend my leg to work the clutch. If I only have to go half way, less work for me and faster shifting.

    I like to not have to think about it at all, and just mash my left foot to the floor and let go...

    ???

    Maybe I'm not understanding your point, but the pedal plate doesn't change the engagement point, it just shortens the travel between "all the way down" and engagement. So, given the same seating position, you would still be "going half way" to engage the clutch, but would not have to deal with the 1" or so of dead space between shifts when you press the clutch pedal and search for the engagement point. You also wouldn't be fully extending your leg, but fully using the total pedal travel (which is now reduced from stock).

    The vagueness is really noticeable in the 1-2 shift under most driving conditions, and especially during daily driving. I could see it helping with launching a car with a heavy clutch too *cough*Fuji... TBone*cough*

    ^exactly, the plate basically moves the "floor" closer to the clutch pedal.

    I am experiencing this with my 992.5RS as well. It seems as though I have to search for the gear to "catch" and it's somewhere in the middle. It's a pain and it does make for more work in driving (my leg gets tired..or maybe I'm lazy?) and I don't get as quick of a response as I would like. I'm still a bit jumpy at times and I'm blaming it mainly on my clutch - or is it because I've only been driving manual for about 2.5-3 months now? :ugh:

    Don't get me wrong though, still the best times ever. :laugh:

    I understand that you are bringing the "floor" closer and that the engagement point of the clutch does not change. Personally I do not need to mash the clutch to the floor to shift. I don't "think" about it either. Back before the 6mt my tranny was cable operated and I adjusted it so the engagement was as far out as possible. I didn't even have to move my leg to shift, just a little calf work.


    I guess I don't understand this "vagueness" you speak of. Am I more in tune with my clutch? I don't see the need to mash it to the floor to shift. In my opinion that is being a sloppy operator. But that's also my opinion.

    Not so much sloppy, but as I expierienced at brainerd a week ago, it was just one more variable that i had to attend to while being on the track with other cars for the first time. The clutch operation wasn't the only thing that I realized wasn't optimal for my comfort level while lapping(harnesses needed badly),it's just one in a list of improvements/additions that I'm going to try to make.

    Take my car for a spin, it's really noticeable in the 1-2 shift with stock clutch... especially when shifting at less than 4k. It isn't difficult to drive correctly, but takes some getting used to and gets really old really fast in city driving.

    I understand what you're saying now though. I agree, under most driving conditions, it's nice to have very little travel and the engagement towards the top of the pedal travel. Other times though... like staging at the starting gates of an autocross, or the staging lines at a drag strip, even the stock clutch gets heavy when you're holding it just at the engagement point and waiting for the go ahead.

    I could see how having the engagement point towards the top of the pedal throw would be functional for performance driving, to a certain extent, also. It would let you move your seat position further back and give your arms more freedom of motion.. but there's definitely a point of diminishing returns dependent on the stop/go pedal positions, short Asian legs, etc...

    True, the stock clutch can get a bit heavy in traffic. I remember the bottom of my foot getting numb at times. That's one reason I put up with the Hyper Single's very narrow engagement window. The pedal effort is lighter than stock.




    As far as the D-Wolf thing, its kinda spendy for what it is. For $50 you could buy yourself a file, hack saw, and small tap set and make your own. But that's how I roll.
