RENNtech is one of the most recognized Mercedes-Benz Tuning companies worldwide after being in business for more than 30 years. Stemming from deep roots in the original AMG tuning company before being purchased by Mercedes, Hartmut Feyhl (Founder) began RENNtech to offer performance upgrades without compromise. The founders at Focus have been proud to have worked closely with RENNtech for the past 6 years and are excited to announce a continued partnership in late 2016. All products ranging from downpipes, suspension, and ECU programming will now be offered in house at our San Diego facility.


All RENNtech products will soon be available on the Focus Webstore for purchase. Be sure to keep an eye out for RENNtech X Focus collab performance packages.
