Yup. easier during parking, clutch doesn't constantly slip. shifting 1-2 less jerky. (not on my car, another one)

It is basically a 'bottleneck' in the hydraulic line to your slave cylinder. It is a fitting with a pinhole which reduces the flow of brake fluid going to and from your slave. This increases the time it takes for your slave to engage and disengage thus 'slipping' your clutch. They install this because BMW must accommodate for female drivers.

its only on the quicker BMW's. i think its like a safety thing. it makes the clutch slip a bit when you shift hard so it doesnt make the car end up sideways on a shift. if you take this fitting out, the clutch is suppost to grab way better and gives you less clutch slipping.
i'm gonna do it on my M.

When I swapped my clutch and had the slave cylinder out, I didn't seem to have one installed. I figured it was only on the M's.
