Bought them here for $150 plus shipping:
BMW x5 4 8IS lowering Links Module Fully Adjustable | eBay
Want $100. I decided to screw around with the computer and now think I'm just going to leave the car stock and order v3s in a few months.
I'll do $100 shipped. I can ship UPS same day. These are unopened and still in the package from the original seller.
My seller record can be checked under the same handle on bimmerforums. Quick and easy way to lower your X.
