Mugen Variable & Showa Winning Suspension 01 March 2014 Administrator Mugen, Vintage & Nostalgia (0) If you've ever popped your hood, climbed into your trunk, or crawled under your car to adjust your dampener settings (was that 4 clicks or 5?), you'll appreciate these electronically-controlled variable suspension kits. Mugen released these quality suspension kits circa 1987 and they allow for convenient SOFT, MEDIUM, and HARD adjustment within the cockpit courtesy of OEM fit-and-finish, dash-mounted switches.

Check out the application and specs- some cool info there!
