The Mugen 5-Way Adjustables (coilovers) are very hard to get hold off, was looking for a set when I first got my EK9, but never managed to track a set down.
However, I do have a set of OEM Honda Access 5-way adjustable suspension kit (springs and shocks - not coliovers), with a 10mm drop to ride height. These are made by Showa Coproration, the same company which make Mugen, Spoon and OEM Honda suspension items.
