Hi,
After having my car for about 6 months now, I swear the clutch feel was getting worse (engagement way too high), even though it wasn't that great when I drove it off the lot. I mean the long "feel" of the pedal travel made city driving a little difficult, and in terms of drivability...good starts from 1st gear were really hard, as the clutch only engaged at the last wee bit of pedal travel. Some of you may know what I am talking about.
Well, today I adjusted the clutch engagement point and...WOW, what a difference! At fist I threaded it the wrong way (about 2 turns clockwise) and the friction point was higher. But when I realized this and went the other way, it really is amazing how much better the car drives!!! I mean quick starts from first are way easier (the cluch doesn't bog down if I don't press the gas to hard). This is the way the car should have been from the start!
I just thought I'd pass this information on to those who are not happy with how high their clutch engagement is....
NOW FOR MY QUESTION (FOR THE MECHANICS/SPECIALISTS)>
By making this adjustment, can I be doing anything to harm or wear the clutch prematurely? I just want to make sure before I drive around with this too long (and I don't want to reccomend this if it is bad for the car). I am certainly not on the end of the thread (on the rod), but although travel may be the same it FEELS way shorter. I just want to make sure as I live by the mentality of "if it feels good, it must be bad" :)
Thanks for anyone's input or experiences, as you can tell I'm really happy about the driveability of the car now!!! I could see for new 5spd drivers, it would be easier to stall 1st with the engagement point at the floor.
Cheers,

Am I reading this correctly?

Your engagement point was at the very top of the pedal travel or the very bottom? My clutch fully disengages with the pedal less than halfway down and doesn't fully engage until the pedal is almost all the way to the top of its travel. I drove a friend's 1st gen Eclipse and the friction point was much closer to the bottom of the pedal travel. It made it much easier to drive, but I didn't feel as connected to the vehicle.

how did you manage to adjust the grab point of the clutch? mine is a bit high also. every other manul tran car i drive have a short grab point so getting use to this high clutch grab sucks. i wouldn't mind haveing it at least half way.

There is an adjustment for the clutch inside the car above the pedal assemblies. Even though it's the clutch pedal you're adjusting, I believe the threaded portion goes through the firewall above the gas pedal...

Sorry, the engagement point was way too high before...now it is near the floor. Way better IMHO...Makes driving in 1st much easier, and shifting between gears feels quicker somehow?! I found the directions here (just do a search in powertrain).
Again, does anyone know if this could harm or prematurely wear the clutch? Looking for comments from Scooby specialists...
Thanks for any input!

depending on how much you adjustted it, and how much it was already worn, you could see some increased wear on the clutch material that's left.

of course, there are many variables invloced, how you drive, how you drove before, if you changed your style with the new setup and how.

but in short, yes, there shoudl be SOME difference in the rate of wear.

My car has under 5000 miles, never drag raced. Did a few 4000rpm clutch drops recently (to feel how fast the car can accellerate). The pedal feel seemed pretty high from the factory, but was noticeably high just after the break-in period.
Maybe I should move it back up a bit to prevent excessive wear?! It just feels sooo right now!
Any comments are always appreciated.
Cheers,

how long have you driven manual tranny cars? it's odd that clutch travel changed that significantly in such as small amount of driving.
from the factory, my car grabbed right off the floor. the top half of hte clutch release was all "empty"

now, at 34K miles, it's slightly higher, but not even halfway.

mine was high off the lot. sort of felt wierd cause i'm used to driving with a lower grab. it seems to change from time to time but that could just be me.

Maybe it was part psychological, could very well be. Others that have driven my car thought it was fine...I don't believe it was worn eccessively...It just didn't feel right to me. I have been driving manual transmisson cars for 13 years. I'm sure I will get used to the way it is now, but I can drive smoothly from 1st now 10 out of 10 times, where as before (the way I drive) 5 times out of 10 my starts from 1st were not great (clutch bog caused hesitation before "going"...this is under light acceleration and day to day driving. My idle is at like 500rpm, though which is lower than any other car I have driven...that may have something to do with it? Does that seem low?
Thanks again for your input.

My 1st-2nd shift seems to change; I don't even know if that's possible, but it sure seems to anyways...

Mine too!!! Sometimes first seems like a high grab and sometimes 2nd too! I posted about this in some other thread. Maybe it's just 'the nature of the beast.'

With all the talk of random bolts on the car being threaded and/or loose from the factory, it wouldn't seem too suprising if the clutch engagement points weren't all adjusted the same...

one of my friends said that in his previous car (non-subaru) he never even had to lift his foot off of the floor when moving the clutch pedal.

do you think it's possible to adjust the clutch engagement low enough so that you don't hafta lift your foot off the ground to get the clutch to engage?

reason being is that its hard to adjust the clutch with precision if you have your whole leg lifted in the air.

my other question - since you can change the clutch engagement point, can you also change the length of the clutch throw? or is that just a result of the type of clutch you use.

If you have one of the first fleet of wrx's then your clutch and flywheel is different then the later wrx's. The first ones engaged much lower and were much heavier, the current clutch starts engaging halfway up and isnt fully engaged till you let off completely, its also light as hell.

Why the low pedal?

After reading through this thread it seems that the majority who responded like their clutch release close to the floor. Why?

If you have to depress the clutch fully to change gears, then it releases close to the floor, you are spending more time pushing the pedal in, which would result in longer shift times, and/or riding the clutch by leaving it partially depressed between shifts.

Don't remember the book title, but it was on autocross. One of the time-saving techniques discussed was to adjust the clutch pedal to disengage at as high a point in the travel as resonable and still allow for full engagement when off of the clutch. It went on to say that once adjusted, you could mount a stop (block of wood) on the floor/firewall, under the pedal to minimize the throw length. This would allow you to make your shifts without fully depressing the pedal. The time savings would likely be measured in 100ths of a second, but, that's what autocross is. A sport of time. It would seem that this same methodology would apply to drag racing as well.

Just something to think about.

Peace,

Curtis

I personally prefer mine to disengage/engage fairly high in the range of the clutch pedal too (high relative to all the way down). I don't think that this adjustment would really affect the wear on the clutch, as it seems to me that it's just the pivot angle that's being changed, not the actual engagement point. (I think that made sense).

Also, Broz, I'd imagine that your car is idling right around 750rpm as the owners manual says it should. Bear in mind that the markings start at 500rpm (not counting the actual zero mark). Notice that the gap between the zero mark and the first one is not the same as the rest? BTW, I made the same mistake. :eek:

Do you have a picture of the adjustment thread? I looked around the pedal, but I couldn't find anything that seemed adjustable. Where exactly is this?

Yeah my clutch is almost fully travelled by the time I come off it. Guess it's normal on the 03's.
Mine too, I've got an 04
