I had considered building my own kit similar to the one Airrdie Systems list.

I fitted lowering links last week. The difference in ride quality within 5mm height difference down low was amazing. Slightly too low and it was really bumpy, but one twist of the links to make it a little higher made it usable.

Still think I'm going down the route of an aftermarket set up. I'll hopefully have Airrex building me some new struts, so they can add the D3 to their application list.
