    Default Multimatic Spool Valve Dampers

    Has anyone - other than Billy Johnson - had any experience with these?

    They sure look nice!

    And they are spec'd on the Mx-5 Cup Car (along with a beefier transmission).

    Spool valve dampers have been around for decades. Pros and cons vs shim stack based valving.

    Aside from their cost I never understood why people race them.
    But obviously I just dont get it. -fatbillybob

    Thanks.

    Looks like a fairly impressive list of users.

    Multimatic's DSSV design has been around for less than two decades, and "out in the public" for less than one. The only cons are far tighter tolerances (microns) in manufacturing which increases cost. Their much larger "production/street" valves in the Z28, MX5, Ford GT, etc... Are less expensive to manufacture than their Motorsport valves.

    They're far more consistent, precise, and run cooler and are nowhere near as sensitive to temperature (oil temp affects damping) as a traditional shim damper.

    Did you ever consider them for any of your personal cars?

    Yup, and the ZL1 1LE among a few more upcoming SUPERCARS.

    Seems like the relative ease of factory tuning the latest generation could be a factor in this increased usage:

    “DSSV damping characteristics are mathematically predictable using Multimatic Specfinder software,” Multimatic explains. “Ideal damping characteristics can be accurately reproduced without extensive trial and error testing.”
