If you lowered it two years ago I am not sure if H&R included the adjustable links then. I just lowered mine after holding off for a while and it had the links. There are after market links but I think you can H&R to send you a pair if it wasn't part of your kit then.

I have looked at other wheels and outside of some expensive aftermarket wheels i really like the style 214's the most for my X5. First car/SUV I haven't put aftermarket wheels on. Lowering really helps it out.
