Porsche Service, Repair, and Performance Specialists

No other Porsche Repair and Service shop in the San Jose Bay Area has campaigned Porsche Cup Cars in Grand Am and IMSA. RennWerks was born from Porsche racing. We are the premier independent Porsche repair shop in the Campbell, San Jose, Los Gatos, Saratoga, and Silicon Valley Area specializing in comprehensive maintenance, repair, and performance services for all oil cooled and water cooled Porsche’s.


These machines of speed and beauty require a unique level of competent and trained technicians to properly service them. We love Porsches and have a deep amount of respect and passion for them.


Rennwerks was started by two individuals that had a passion for racing and were frustrated by the lack of capable Porsche service and repair shops in the South Bay Area of Mountain View, Sunnyvale, Los Gatos, Saratoga, Campbell, Cupertino, Santa Clara, and San Jose. The two talented drivers, who loved racing Porsches, had met during several club racing events, In 1996, they were chatting over some food and beer at a local bar and decided to pursue professional racing in the American Le Mans, and Rolex Race Series. They achieved many honors and accolades and shared the Podium with the Porsche Sponsored Factory Teams. RennWerks was created to supplement their operations and to service the automotive maintenance and repair needs of those individuals who are passionate about their Porsche.
