Ultimate Clutch Pedal Home - Ultimate Clutch Pedal
It's a metal pedal arm and it has nice brass bushings. Expensive, most people say it's not worth it but it was definitely one of the better things I did to the f30. The first drive was very noticeable.
They say it doesn't fit E39, which is the e53 pedal pre/post LCI. Bummer. Maybe somebody makes some brass bushings or something but it'd be rather pointless with the plastic pedal. I'll look into this more.
