Here is a link to them:

But I had a Z3 with the BMW oem ones that looked like this and like those just a bit more.
The **********s pedals were in a box labeled bimmian.com, so you could get them there too.
They were under $100 and easy to install.
The BMW ones had replaceble inserts and the screws were countersunk.
The **********/bimmian ones has hex screws which did not fill up the screw holes. I am maybe being picky but it would not have been hard to machine the holes to be just a bit larger than the screw heads.
Also there were no instructions at all!
I've done it before so I knew what to expect, but it would be nice if there was some leaflet with some simple instructions..or even a PDF on-line.
I like them though and dont notice the screws from a seated position. You would have to get on your knees and stick your head in under the steering wheel to notice.
Also they said Z4 has no dead pedal, although their website seems to make it look like there is. So if you want the full set look somewhere else, unless you dont mind a mismatched set.
I will take a picture after lunch and post it up for you.
As a side note: if you have aluminum interior these match great!
