Morning guys,

Is there anywhere in the UK that I can source a clutch stop - like this:

http://store.uucmotorwerks.com/clutch-stop---big-boy-v30-p41.aspx

I used to have one in my old Z4 and it makes a big difference IMO, there is definitely a dead spot on the standard clutch pedal travel wise.

Nice one :thumbsup: I've emailed them to ensure the Z3 one will fit the Z4.

When I go to checkout it doesn't seem to work. Hmmm, wonder if they're still in business. The Z4 section doesn't seem to work either.
 
Works for me - comes to £14.95 with the discount as they apply the 30 % before VAT. Very generous.

If you look on the UUC site it does not list the Z4 either, but it does say it is the v3.0 big boy, which is the same as the one I found.
 
Doesn't work for me in IE or Firefox. It could be something to do with my work pc and the filtering they use here. I'll try at home tonight.

When I try to checkout it goes into a loop: (I've not pressed back)

"It looks like you have used the Browser's Back button to navigate to the checkout page. Please start the ordering process by using the "Checkout" icon. Please wait for your browser to forward you to the next page or click here. "
 
I am using safari on an iPad, so I think it must be the filtering on your work PC / internet as you say.
 
Graeme,

I made my own with a bolt, a few nuts and a rubber foot for a chair. I already had the nuts and bolt and I had to buy a pack of four rubber feet from Homebase for a few quid. If you want to do the same, I'll send you one of the rubber feet FOC. :thumbsup:

I did the same using a nut and bolt. I altready stuck the existing bump stop to the bolt. This however soon fell off. I left it that way and it still isn't noisy to use!

Hi John,

Actually that's a good idea and much more satisfying than just buying one. Do you have a picture of it? Any idea what the thread is of the bolt? I could take a look around B&Q and see what I can knock up :D

Otherwise I'll take you up on your kind offer :thumbsup: :thumbsup:

I never thought to take a photo of my clutch stop. The bolt was a galvanised M10 x40mm and two M10 nuts. Both nuts were threaded on to the bolt before fitting; the second nut was used to tighten when the stop height was fixed. The other nut was set so that the rubber foot fitted best over the bolt end and the nut.
 
As someone who finds getting consistent smooth gear changes in the Z4M quite difficult I'm interested in this modification, but I have never fully understood what this modification exactly solves. The 'biting point' of the clutch stays the same, as long as this is memorized in your left foot what does the clutch stop bring in practice?

The biting point of the clutch seems to be a a good inch off the floor and the spring force of the clutch pedal seems to be quite strong, so sometimes your left leg gets a bit tired and "forgets" the precise position if you don't keep your left heel on the floor when releasing the clutch, especially when driving slowly in tailback traffic: this can be difficult for those of us with small feet. Therefore, if you put the clutch stop at a point just below the clutch biting point, as long as you press the clutch pedal to make contact with the clutch stop, you simply lift off to release the clutch. I was sceptical before I tried it, but it does work.
 
^ As above :) I had it on my last Z4, big difference.

I need to get this done.. full of good ideas at the moment not enough time. Also need to do your airbox mod John :thumbsup:
 
I made my own in about 2 minutes and its probably the best mod you can do to a Z4 and it costs nothing, It makes them so much easier/nicer to drive. :D
 
How do you know how far you can go, in other words how do you guarantee that the clutch is fully disengaged under all circumstances?

Immediately before you remove the OEM clutch stop and have everything ready to fit your DIY clutch stop, have the engine running whilst the car is parked, then engage 1st gear, and take a good note where the clutch biting point is. Then fit your DIY clutch stop, and with the engine off adjust the stop so that the stop is about 10-15mm below the biting point. Then switch the engine on and engage 1st gear again and by feel note how much below the biting point the stop is and adjust accordingly, so that you've got about 7-10mm clearance where the clutch is always disengaged when the clutch pedal touches the stop. Provided that you always change gear by pressing the clutch pedal against the stop, you'll always be completely disengaged.

After driving the car for a while in all types of conditions, you can fine tune as necessary.:thumbsup:
 
Clear answer again Exdos, thanks.

To further improve gear changes I'm also considering VibraTech engine mounts, would you recommend that for 'fast' road use or do they only make sense on the track?
