But I'm interested to know more about the UCP. Did you install it, or a shop? Did you go through a progression from clutch stop to CDV delete to UCP? Etc.

Asking because I'm really trying to straighten out the pedals (for track mainly), and if this would be helpful I'd certainly put it back on my punch list.

I have a thread on my clutch travails:

http://www.1addicts.com/forums/showt...hlight=bushing

"Brief" summary:

The BMS Clutch Stop was one of the first upgrades I made to my car.
Definitely appreciated the shorter throw, but was still bothered by the delayed reaction and jerkiness, as well as squeakiness of the bushing.

Installed one of the CDV Delete valves. Was very happy with clutch response, but still annoyed by squeakiness.

Installed the AKG Delrin bushings. P-I-T-A. They were a little oversized - need to make 'em less wide to get the c-clip back on. Over-center spring was a nightmare. Cracked one of the pin retaining rings = broken clutch pedal. Went back and forth on "stock pedal but pay someone to do it" or "UCP and DIY." I went the DIY method of the UCP.

SOOOOOO much easier to install than the stock pedal! Not even funny! 45 minutes of futzing around vs 5 hours of beating myself up.

The UCP has some captive bronze bushings. I polished 'em a hair with 2500 & 5000 wet/dry then Mothers Mag/Aluminum. Cleaned up 'em and greased with Redline Moly. Not sure where the AKG bushing are right now. Don't care.

It also came with a nice big clutch stop. I went nuts and used the full UCP stop with the full BMS clutch stop. Car wouldn't start - clutch didn't disengage fully. Pulled out one layer of stop and have had no problems and just love it.

UCP is slightly grittier-feeling than the delrin AKG bushings were - slightly - but this thing never binds, never squeaks, and is completely 100% consistent. I put the spring in the middle "sport" position and have not tried "comfort" or "track" because, frankly, it's just right.
I haven't measured it, but while travel is shorter overall there is actually some overtravel on reset once the clutch is fully engaged. But the feel is great, it's progressive, easy to modulate, quick, sharp, and like I said, consistent. No slop, no give, no bending or shifting. Brilliant.

DIY is still a little bit of a pain. I found it much easier, and better on my back, when I placed an ottoman just outside the driver's door to rest my lower body on. And nicer with my 10 year old handing me tools and finding the one that rolled underneath me. Worst part for me, really, is I have a 6+ foot wingspan and when I stick my arm up in the pedal box my fingers are above everything I want to work on. So I had a kink in my wrist for a little bit... Using allen-head bolts instead of pins to secure the springs was a stroke of genius.

I haven't tracked my car but, knowing what I know now, I wouldn't do it on the stock pedal/stop/lock valve - but wouldn't hesitate on my current setup.

If you've got the itch, and the scratch, do it. You won't be disappointed.
Every day I drive my car, I say to myself "Wow. I LOVE this clutch."

Damn you've got me thinking about the UCP...I remember reading your original thread but that was before I had the BMS stop and CDV done.....now that they are, the clutch is way better but not quite where I want it. It's the difficulty modulating and (lack of) consistency that makes me crazy...

Though noticeable, it didn't make me that crazy on the stock pedal.
But that's where I feel the biggest improvement with the new one!

Burger Motorsports - who makes the delete valve - is in Simi Valley.
If 2 hours is too far to go, they should be able to refer you to a nearby shop that handles their stuff.

Thanks a lot. BTW, after I posted this I read in multiple places that the M3 actually does NOT have the CDV.

You know, I think you're right!
I've never had an M3, and this is the 1 Forum, so I hadn't really thought about that. Anyway, it's easy to check - if you don't mind getting underneath the transmission.

Just performed this. Wow!!!
Should have came from the factory without the CDV. It feels like a race car now and I am really enjoying every time I shift.

Glad I do so much reading in this forum now that I have a 135i and I found this thread. SSK and Clutch Stop were already planned but the CDV delete is now happening this weekend along with a few other things! Thanks for all the great information everyone!

I'm not a fan of a clutch stop... but a CDV-delete and a SSK is a MUST!! It totally changes the way the 135i feels. Our cars should have come from the factory this way. I think BMW realizes this because the M2 does not have a CDV!

PS: Then all you need a PE(Performance Exhaust)!

Good thing is, if I do the clutch stop and don't like it, super easy to switch it back Thanks for all your input Dack!

Hello everyone, just a quick question.

I did this today (complete delete - looks like pic 5) and what i did was reuse the clip from my CDV but i noticed that with little (but not minimal) effort, I was able to separate the two. I was wondering if this is normal. Thanks in advance
