The biggest difference for me was that sometimes when I thought I hit a perfectly timed shift, it wasn't smooth. I blamed myself (what else could it be), but once I did the CDV delete, my perceptions and reality merged.
Ok got it. Thank you

Just an adjustment update,

I had originally set it using all factory springs on the "race" setting. At first I liked the firm engagement but after a month of use I came to loathe the "poppy" nature. It made the shifts from 1st to 2nd around town a bit too jerky and hard to control. I found myself spending too much leg energy "managing" the pop point rather than enjoying the drive.

Talking with another user of the UCP and he had removed the large spring and put it on the sport setting and that was perfect for him.

I spent today trying all the settings with test drives back to back. I tried removing the larger spring, in the sport setting. Felt decent. No more pop.. but a bit wobbly at the top of the pedal.

I then tried it in sport with all springs - this is the most popular setting from what I read on UCP threads. It stiffened up a bit, but undesirable "pop" returned.


Then I tried all springs with the "stock" position. No pop, Felt very much like removing the big spring in the sport setting but more stable at the top of the travel and a bit more firm.

I ended up with the "stock" spring position with all springs. The travel feels smooth. No wobbles. There is no "pop" point like in the other settings. I think this is the ideal geometry for the assembly. I believe the big spring adds rigidity to the assembly, takes out play, and adds slight stiffness to travel. Moving the pivot point towards the arm increases stiffness but also pop, which I did not like.

The UCP benefits in the "stock" setting are still a shorter travel and better pedal position which is what I was after.

Hope this is helpful to those of you who want to tinker with it. Don't be afraid of the "stock" setting like I was. It is still a major improvement over stock pedal.

This is very helpful. The pop sometimes just drives me up the wall in casual non aggressive driving situations around town. Going to try this next.

Very interesting. How did you adjust the over-center spring positions? Did you have to remove or uninstall anything (like the master cylinder pin/bolt)? I may have to try this...

Yes I had pop out the clutch cylinder shoulder bolt and disconnect the light spring each time. This gives the pedal the freedom to easily reposition the over center spring.

Hardest part of this is getting the clutch cylinder shoulder bolt out each time, it's a bit of a snug fit. Use your socket wrench to tap on the end of the threads to knock it loose and you won't have an issue.

You sweet beautiful son of a b****. Just did this tonight, and the pop is gone. Finally! (Although after accidentally putting it in the race position and having my arms fail me lol). Thanks!

Glad it helped. I have to say. I was driving today and was having an absolute blast with my mind off the pedal pop - much more smooth experience.

Can you guys post pics of your pedals... mine is so crooked, but I can't imagine I messed up the install... and the function has been normal, without any issues

Mine is slightly crooked but the position and feeling is perfect, and since I don't look at my pedals ever, I was cool with it.

Today was the first full day with it, and you are right on. Much more pleasant experience without the pop for every day driving.

Hi, I just want to make sure I understand correctly about the placement.

The holes that you are referring to are:

Stock (Farthest from Pedal, closest to Engine)
Sport (Middle Hole)
Race (Closest to Pedal, Furthest from Engine)

Is that correct? Thank you!

I put mine in the middle, because, well it's the middle. Not too this, not to that. I'm super excited to try out stock this weekend. The whole clutch/shift experience has slowly been bothering me more and more. Hopefully this will help! Thank you for trying out various combinations!

I changed my UCP to the "stock" spring position today. Working in 90 degree, humid Houston weather. Got in to test drive and car won't start! It gives me the "Depress the clutch to start the car" message. Of course I was doing that already, so I pumped the clutch a bunch of times, but it didn't help. Had to stop for the day, so wasn't able to troubleshoot any further.

The only things I can think of are;
Air in the lines, needs more pumping?
My clutch stop needs to be less thick, now that I am in the new spring position?
Somehow in my haste I missed the eyehole when attaching the master cylinder to the ucp with the bolt? Hard to believe I would have done that, but it's possible.

Anyone have any ideas?

That's odd. I just did this switch earlier this week with no issues after. Full clutch stop and stock position. I'm a bit stumped because I don't know what you could have done that would have impacted it like that. Nothing you did requires clutch bleeding or electronics.

If after removing clutch stop it still doesn't work, that ain't it and it's probably electrical or a master cylinder issue.

The only things I can think of are;
Air in the lines, needs more pumping?
My clutch stop needs to be less thick, now that I am in the new spring position?
Somehow in my haste I missed the eyehole when attaching the master cylinder to the ucp with the bolt? Hard to believe I would have done that, but it's possible.

Anyone have any ideas?
Likely you forgot, or missed the bolt hole in the end of the clutch cylinder. Check / re attach the shoulder bolt through the bolt hole at the end of the clutch cylinder. It has some play in it to aid alignment but possible this play had you miss it with the shoulder bolt and now when you press the pedal it's not actuating the cylinder all the way.

So, it turns out that a wiring connector to the clutch cylinder came undone when I was removing the footwell cover plate yesterday.
I didn't realize it at the time and when I saw it yesterday just thought it was a wire bundle and I pushed it off to the side out of the way.

Today I figured it out, connected it and voila, car started up!

Took it out for about an hour test drive and I agree with everyone else that the pedal travel is much smoother. I like it and am happy!

Just moved mine to the 'stock' position. I do like it better! It feels more linear to me, and more forgiving. The 'pop' or springiness is all but gone, and it does feel like 'stock', but shorter, more firm, more precise. I guess that's why there are 3 positions; to each his own I just can't believe I never thought to try this! A big thanks to you guys!

Has anyone tried or compared the UCP pedal vs the Turner pedal? I have a UCP pedal that came with the car (M2 CS) but am not really satisfied. My issues are looseness at top of travel, crooked pedal position, and light pressure/springiness. I’ve read through this thread and it looks like there are some things I can try to adjust but just wondered how the UCP compares to Turner. Thanks.

Have you double checked that it was installed correctly? Some people didn't install all of the springs (for various reasons), but that can affect how solid the UCP feels.

It definitely does not sit crooked and there is no looseness at the top (in fact it removes what little looseness was there).

Most all modern clutches are light. You might try the different spring positions to adjust the level of springiness; i know it helped me.

Also, did you use the proper clutch stop? You can't use a soft one like the Burger one.
