I am putting together a group buy for these as well as other running boards for both the x5 and x3. Anyone interested please check out the group buys section on the main forum page under BMW Related Forums.

In response to NOVAX5 and Brit6: these are a fantastic inexpensive alternative to the factory running boards and require a fraction of the install time/effort/cost. They might not provide as large a stepping area but they do give added traction and there is plenty of room to stand on them and they are strong enough to handle as much weight as the stock parts they bolt on to. As for the dangerous claim these are secure if installed correctly and I have yet to see an actual incident of them flying off.
The OEM RB look aweful from side angles as they stick out beyond the fender flares and wheels and have the potential to catch on either clothing/shins or curbs/barriers. And as for buying from a discount dealer, Morristown BMW who advertises on this site don't come close to $550 and their labor is $120 and hour. They happen to be a somewhat local dealer of mine and I often use them for parts and actually purchased my first BMW from them years back. BTW FYI their service department is bureaucratic and negligent.
