California Motorsports Billet Side Plate Porsche 911 65-68

California Motorsports have established themselves as the leaders of Porsche transmission repair, rebuilding, service, support and development for more than 3 decades. The continued success comes from the very own in house R&D, allowing them to produce high quality transmission parts.

California Motorsports has a replacement for the factory cast magnesium plate known to be problematic with its very own CMS Billet Plate. The original magnesium plate where known to crack, have loose or out of round bearing bores or even worn out shift shaft provisions. CMS saw this flaw and like many of there projects, took it an re-engineered it to a better more quality design that billet gives.

The CMS Billet Side Plate is perfect for street, race, higher horsepower and V8 applications-where the additional strength is really needed. It is precision machined from aircraft grade billet aluminum to exacting standards for a perfect fit and function. Along with some silicone bronze shift rail bushings, that can be easily replaced.
