How can pressing clutch pedal be so lighter? than stock after modding.

How can pressure i have to apply on clutch pedal is so much lighter than stock after changing lightened flywheel and clutch disc?

Clutch disc is just like stock one (Exedy organic ), with same pressure plate. ( replacement )

It almost feels like there is no resistance, with my left leg.

Is this something to do with bleeded?

Is this Adjustable?

Mine is lighter because of a springless clutch plate. The spring should be on the clutch disc so I think yours are springless too.

I am not sure what makes it lighter other than this.

The springs on the clutch disk should have no effect on pedal weight. They are for shock absorption on engagement.

katana4eva:
has the clutch take up point changed? When I changed my clutch and flywheel the engagement point was very close to the floor so it seemed light. I had it adjusted to a more normal position for drivability.

If your happy with the way the clutch is engaging and it feels normal apart from being light, then it should be ok.

why take up point changes will change the pedal weight.

I may agree that spring may have nothing to do with it. But I really cannot see the reason if he has not change the weight of any movable part of the clutch. Spring is the only part that has changed right?

Thanks for answers!

Springless..hm not sure about it.

clutch take up point has changed as well.

not closer to the floor... but rather in opposite direction.

It's almost at off position. ( left foot almost off the pedal )

Because of this... i had problem with reversing at first time..lol

Adjusting it to deeper position ( more closer to normal, similar to stock ) is it big job? like where you have to take out the gear box again....?

It's not just take off point. ( changed but in opposite direction to most of people saying.. ' closer to the floor ' )

It's the weight.. changed. I will have to ask Ric, whether it's springless.

Perhaps my left leg became super strong in 3 days :p


Let 1 be left foot off the clutch pedal

Stock take off point was about 0.4~0.6 ( not sure, just my opinion )

After changing flywheel+clutch disc, take off point feels like 0.75~0.85

And pressure i have to apply on clutch pedal is about 70%less than stock one. Maybe even more. feels like throttle pedal

would there be any disadvantage of being clutch engagement point being quite a bit higher than stock? if I get used to it?

since a lighter clutch isn't a bad thing and the take up point is just a matter of preference there is no real problem with the clutch.

have the take-up-point adjusted to your preferred position if you want it will just make the car easier to drive.

Taka: I think the lower engagement point caused 80% of my clutch to be dead travel. so for all that travel I was just putting force on the pedals mechanism and only moving the pressure plates springs for the last 20%.
any change in the take up point will also change were the load is in relation to your leg muscles and the force they can apply. it would be the same load but can feel lighter due to a better position where you can apply more force.
just my reasoning

the clutch disk springs may indeed change the pedal feel at the take up point even though your not directly acting on them.

If the clutch take up point were to be deeper, you're increasing free-play in the clutch? Thats the characteristics of a worn clutch, so I'd think youre clutch is healthy with the take up being right at the end?

But as far as I know, you can adjust the free play on the clutch (service manual).

Ric installed my clutch as well with an upgraded pressure plate on an exedy stock disc. The pedal's soft when car is cold, but alot more resistance when warm, I can't understand why?

Haha same as mine.

All I can say is much appreciate the take up point being at the top, feels new again.
