I took a look at struts. These are pretty important on a BMW and contribute a lot to the ride.

I would use Sachs, Genuine BMW, or Bilstein (not the harshest model) only
I would not use Monroe, Duralast, etc.

The only one I think you could source THIS WEEKEND is genuine BMW from a dealer parts desk..and man, is that pricey..maybe 2x what OEM from FCP ould be. .If you are a BMW CCA member, you can usually get a discount. Otherwise take the car off the lift, and order what you need from FCP Euro or other.

Can I suggest you add something more descriptive to your titles other than just "Help"...
Maybe " Help need decent struts this weekend"? You also need to identify which model you have and whether it has sports suspension..
