Mason Engineering Z3 Clutch Pedal Review

[Niswonger]

I'm in for the GB at 220 as well as a brace.

[Eurospec]

How does one get in on the $220 deal? Ok for us canadian types?

Shipping across the boarder shouldn't be a problem. It'll just translate to an extra shipping charge.

So the only reason that you are recommending the OE bushing is for "direct" fit, versus the light modification the Oilites need?

Nothing to do with operation?

That's correct.

I am in for the $220 + deal if possible.

Will add you to the list. We could even arrange pickup depending on where you live.

Count me in on the GB too.

Sure thing.

i'm in for $220 also... standing by

I know it was discussed by the OP... but i'm simple.
but so i'm clear: additional parts needed are as follows:
I.E. oilite bushings (modified) or delrin bushings supplied by UUC or stock, plastic bushings p/n 35 21 1 158 290
new spring, p/n 35 21 1 158 489
Two rubber grommets, p/n 35 31 1 113 725

also, any idea how much material needs to come off the IE bushings? i'd like to go that route..

Yep, those are the parts required. A minimal amount of material needs to be taken off the bushings. It could even be done by hand with fine sandpaper.

I'm in for the GB at 220 as well as a brace.

Noted.

For all of you who have expressed interest: Expect an official GB to open in the following days, at which time a new thread will be posted.

I'll watch for the group buy. Thank you for putting it togeather!

[MartyBtoo]

If you're going to do a group buy, how about a second option; the Mason pedal assembly with installed oilite bearings. Even better, include the spring and the two grommets; a one-stop installation kit! I'd be up for this.

As much as I'd like to provide the option for an all in one kit, I feel that would complicate matters on my end. I do have an additional set of IE bushings that have been modified to fit the pedal. Let me know if you'd like to claim them.

Count me in.

I'll take the IE bushings if for some reason Marty's a pass.

Update on bushings:

I came across a set of Garagistic brake/ clutch pedal delrin bushings (blue) I had set aside for my E30 and they fit perfectly. The UUC's required some effort to be pushed in completely whereas the garagistic bushings slide in easily. With a light coating of a PTFE/ teflon based lube, these would work great.

It appears garagistic has changed the color of these bushings to yellow, LINK

Yes, I'd love to have the modified oilites; add them to my reservation for a pedal! Thanks!

[BIGSOOJ]

Thanks for setting this up!!!!!! The group buy should be great

[Tom Liberatore]

Any idea when the buy will happen? I'm ready!

[MartyBtoo]

Just for the hell of it I ordered the spring and the two bushings from my local BMW dealer; came out about $16 plus tax, should be here tomorrow.

Count me in on group buy as well.

Also in for the GB.

Are these the I.E. Olite bushing you guys are using?

Also, since I'll be in there installing this clutch pedal arm, would you guys recommend doing the brake pedal bushings?

Yep... those are the bushings.

Great opportunity to replace the brake bushings, indeed.

The Mason pedal comes with the necessary hardware (bolt, locking nut, washers) to mount to the clutch actuator. OEM type bushings are also supplied if you choose to install these instead of supplying your own. Once the new pedal is in place it will need to be secured to the actuator and the metal bracket reinstalled. One of the last steps involves installing a new spring with grommets. ...

Some additional parts are required for the conversion. The clutch pedals in Z3M’s come with a barrel type spring. This spring is eliminated altogether and replaced with a return type spring found on non M’s and some, if not all E36’s? The new spring, p/n 35 21 1 158 489, mounts in a different location towards the top of the pedal. Two rubber grommets, p/n 35 31 1 113 725 will also need to be sourced and installed. This will all become clear once you start disassembling the stock clutch pedal and compare it to the new setup.

OK, just to clarify: as these are BMW OEM part numbers, and you say that the Z3M stock clutch needs to be replaced and fitted with a "new spring" that's "found on non-Ms"... Does that not mean that I, someone with a base model 2000 Z3 roadster, already have this spring and grommets on my stock clutch?

Yes, BMW part numbers. Chances are you have the correct spring. Removal of the kickpanel and a quick peak will indicate otherwise.

Sorry about the confusion. The review/ how to was based off the conversion in my M Coupe.

Great, that's how I read it too, and looking up my car at oemparts indicated those parts were my stock ones... Just wanted to avoid trouble with assumptions and all

[Vintage42]

... I had the oilite bushings in my hand and tried to install them. The outside diameter is just a tad too large and required some sanding...

My bronze bushings fit easily in the Mason pedal that I just received in the second group buy. I assume they are oilite (sintered oil-impregnated bronze). Got them from Bimmerbum.com a few years ago.

Excellent finding. Simplifies matter greatly.

[Vintage42]

I installed my pedal yesterday and was able to swap the Ireland Oilite bushings from my stock pedal into the Mason fairly easily; the bushing bore in the Mason pedal needed some mild cleanup (mostly powder coating residue) with a sandpaper roll for a good press fit....

My bronze bushings fit so easily that they fall out. I plan to use bearing grease inside and outside. Oilite sintered bronze is dry metal, even though it is impregnated with 30W motor oil that you can't feel. And bearing grease seems more compatible with that oil than the white lithium grease that is used with the plastic bushings.
Did you remove the seat to replace the pedal? I removed the seat and started into the bushing replacement two years ago, but gave up because I had trouble fitting and seeing upward under the dash. 200 lbs, 6'-2", old age and trifocals. Will try again now.

Although I went with the recommended 35211158489 return spring, I also made sure that I could install the OEM M-style over-center return spring just in case I wasn't happy with the spring change; the pin bore in the Mason pedal for the over-center spring assembly needed to be opened up slightly (not just power coat) for the pin to fit.

This is great news. One of my hesitations in switching to the Mason pedal was the use of the Z3 return spring. I've had that before on my M and it was too firm for daily driving. It was such a nuisance that I switched back. Good to know that it is possible to use the over-spring setup with the GSP pedal.

Pedal installed - greatest thing to happen to everyday motion in this car. Absolutely love it. Thank you for hosting the group buy!
