Hey guys,
I know that this is a super talked about topic but out of the dozens of threads I've searched I still haven't found an answer so I figured I'd start my own thread.

Anyway, my clutch engages at the very last minute. Like half inch from the top of the pedal height. It was like this when I bought the car at 116k miles. At that point, the clutch was so worn out that it slipped when I went up a hill. So I replaced that with an ACT street disk, and while I was in there I got a new flywheel (11.5 lb) and pressure plate (ACT heavy duty). Many people have said that the height that the clutch engages at goes up with wear, which makes sense, but the height did not change even with the new clutch. So ok, I'll go ahead and adjust the rod under the clutch pedal. Nope. Still releases super high, even with it set to no free play (don't worry, that was just an experiment, back to about 1/4" free play as of now). I did gravity bleed my clutch fluid as well, but that didn't really make a difference.

Any ideas? I've heard that some people have been able to have their clutches engage lower, which makes me think that this isn't just how the car is. Or maybe each S2000 has its own unique personality, in which case I can live with it

Thanks a bunch for the help,

More freeplay = lower engagement.

Because instead of pushing the slave cylinder, you're just pushing through freeplay. So more freeplay means the slave cylinder moves less. So...later disengagement, earlier engagement (all the action moves toward the floorboard).

But you risk not being able to disengage the clutch all the way between shifts.


6mm freeplay is the spec, so that's really where it should be for proper operation. Make sure the actual pedal height is set properly also.

Do you want this thing to engage at the floor? Or are u just making sure your car is alright?

 

Generally the s2000 clutch engages higher than other cars

 

Thanks for the reply. That does make sense yeah. Ideally, I'd like it to engage more towards the floor, but I do want to make sure the car is alright as well. I'll definitely take a look at pedal height, too, didn't think of that! Will report back any changes I can make.

And yeah afzan, I have heard that. If that's how it will turn out to be then so be it!

 

btw since you mentioned the ACT HD PP, you should look into bypassing the clutch starter interlock so you can start the car without pressing the clutch (upgraded PP causes more thrust washer bearing wear)

 

Oh that does make sense yeah. Thanks again for the info!

 

I don't know if you'd like floorboard engagement on a car with like 0.002 LB of torque that has an extremely light flywheel and short shifter throw.

Floorboard engagement works well on cars with a lot of "give" in the clutch, lots of torque, and big clunky drivetrains.

Like a farm tractor. Or a Nissan.

A proper sports car has engagement up top. Results in faster, easier shifts.....gives the car a "lighter" feeling...allows more time for you to get the engine spun up from a stop, etc.

Each person has their own style and preferences. But...I think it would be really contrary to all of this car's ergonomics to have a floorboard engagement.

 

Yeah that makes sense. I don't want it all the way down, but like 2 inches from the top would be perfect.

So I tried some adjusting today, didn't make any progress but did notice something. My pedal only sits 6" from the backboard. I attempted to raise it up by changing the clutch sensor switch back, which raised it to about 6.5", which is still short by about an inch. Furthermore, this made that pushrod threads engage by only like 2 threads, so I had to move it back, no way to remove the excessive amounts of free play. Any ideas about how to change the height?

Thanks a bunch.

 

Something is off here. I think your issue is indeed clutch pedal height adjustment. But you can't get to proper height as adjustment rod isn't long enough (rod adjusts free play, height is adjusted by the pedal stop).

Maybe someone shortened the rod?

Maybe the whole pedal assembly is modified? (Like a po modded due to extra long or extra short legs or something).

 

Yup you've got it exactly. Maybe it is, because yeah most I'm getting is 6.5". Maybe I'll take it to a Honda dealer and see what they think. Thanks for all the help!
