My M Coupe came with a spare set of H & R springs that I won't be needing.
But they would need to be collected from GU47 as the fronts are still attached to the OE shocks that date from 2006, but the springs are obviously much newer!
Let me know if you'd be interested in them or would like to see photos.
I've got some H+R springs about 25000 miles on them, good condition. Off the car and ready to go. Where are you located?
Feel free to make me an offer.
