Thanks for the quick response. Installed the regulators Friday afternoon after work and I swear it took less than 30 mins per window.

The materials BMW used in these regulators might be crap, but the design and ease of replace is outstanding. I've had windows in other vehicle come out of tracks or tilt forward and need adjusting. None have ever been as easy as this... BMW's the BEST!
