PCA Announces New Spec Boxster Shock Package

[thstone]

From the PCA;

The Bilstein PSS9 shock, which is the spec shock for SPB, is no longer available, and it appears that parts to rebuild this model shock are also NLA. The SPB rules are amended to add the Motion Control Systems SPB damper, part number SET-1WNR-SPB-01 as an alternate shock for the class. The aluminum upper rear spring seat and the tender springs and separators may be aftermarket parts so long as they are substantially similar to the PSS9 part. Minor trimming of rain gutter sheet metal in the rear trunk above the shock adjuster to improve access is allowed.


Here is a link to all of the details with shock dyno results comparing the PSS9 to the new MCS. Existing Swift springs will work with the new shocks. New springs will be aftermarket from Tarett. Shock package is $2,650, New springs are $875.
