Poll-I'm putting a clutch assist spring back in, and this is why

I'll try one more time, then I'll let it go...WHY don't you like it? You have to have a reason.

I'll chime in here. The pedal slop is just unnecessary. I am driving a fairly expensive sports car, and for me personally I would be embarrassed to let someone try the clutch on this car the way I'm driving it right now. I notice when I went out this weekend I had to catch myself while I was wearing my nicer shoes from pulling the pedal up with my foot after each shift. I love every aspect about the car except for the clutch assembly, the trans, and the shifter.

If the spring eliminates the slop and is not noticeable, I would rather have the neatness and peace of mind about clutch wear over saving 20 bucks or however much the springs cost.

@GT Pony Which is why I'm kinda pushing you. Why are you sold out on these springs when you really don't know if they are going to be the cure all that you are claiming them to be?

Because knowing how the assist spring works, it makes engineering sense that using the soft spring will ensure the pedal is all the way up at all times, and still allow the the clutch pedal to feel like it does with no spring at all.

As the pedal assist spring stiffness keeps going higher and higher, then you will obviously start loosing some feel ... that's why a 20 lb spring (minimum I would consider using) would give you the best of both worlds IMO. Just strong enough to always keep the pedal fully up, but not strong enough to notice any assistance.

Someone ordered up quantity seven of the 59 lb springs (discussed in the other thread) to try and hand out to others to try, so give it a few weeks and maybe we'll hear how they think that one feels.

What part of post #8 don't you get?

Why you don't like the slop. All I'm hearing you say is "I don't like the slop because I said I don't like it". My bad I guess. We're talking past one another, no worries it's all good.

The little slop I had went away when I installed the McLeod clutch.

See post #16 - same reasons. Also, as I already said ... IF for some reason there is negative results of having pedal slop, then with the soft spring that unknown is taken away. I see that as a good insurance.

This same exact thing about removing the clutch pedal assist spring would also came up on the C5 Vette chat boards. Lots of guys were doing it. Then one day a GM engineer who worked on the C5 design chimed in and said there was a reason the spring kept the pedal all the way up. That reason was so there was no possible movement of the hydraulic clutch cylinder plunger from being moved inward at the slightest while the clutch was up. Regardless if that put any pressure on the throw-out bearing or not, they didn't want it moving in at all unless the pedal was actually being depressed by the driver.

[MENTION=14534]GT Pony[/MENTION]. Lol engineering sense! I work with engineers everyday, building, fixing, re-engineering their "sense". Let us both wait for some real world results. Peace

LoL ... without engineers, we'd all still be living in caves and walking around aimlessly. Do you really understand exactly HOW this assist spring works?

Watch closely how the spring compression (ie, it's force) changes as the pedal goes through it's travel. Pretty easy to see how it works, and that a soft spring will keep the slop at the top out and yet not add much assistance.

I guess at this point I am one of the lucky ones as well because I don't notice any slop at the top. As long as there isn't any real world problems that people are having with not having the spring in, I will not put a spring back in

GT Pony · Jan 12, 2016

Here's something I want to point out. Notice in this video that there is also a torsion spring on the main pivot of the clutch (and brake) pedal. Notice when he removes the assist spring that the pedal will still return to the top on it's own. Therefore, when those guys removed their assist spring, then did NOT have any pedal slop at the top because the torsion spring was holding the pedal all the way up.

In the S550, there is NO torsion spring on the pedal pivots. If he was doing that same demonstration with the S550, the clutch pedal would be flopping all over the place. Therefore, that is why a softer assist spring needs to be used on the S550 if you want the slop out of the top of the pedal.

Curious about common availability of this softer spring? Was it noted within another thread?

Hey thanks GTPony, l see the term slop and play both being used to describe this. So is this where you can like grab the pedal and feel this slop or play?

Edit: Just checked, have about 1/2" so l answered my own question.

Subbed as i dont want an assist spring but slop on a clutch would drive me mad. Softer spring may be the answer.

No real consensus on the poll. Bumping for more votes.

Poll-I'm putting a clutch assist spring back in, and this is why

Why are you putting in softer spring?

pedal too firm with no spring

concerned about premature clutch wear

just dont like the extra play in pedal with no spring
