John was Chief Engineer, Advanced Chassis-Vehicle Systems at Navistar (International Harvester) and in 2012 the company moved operations to Chicago, IL. John and his family chose to stay in Indiana and to pursue his dream of developing aftermarket performance components with his engineering consulting company, Hoosier Performance Engineering. While working on some projects with DTE Performance (prior Dynotech Engineering) of Fort Wayne, IN, the owner of DTE asks John if he would be interested in buying out his business. In November 2013, John and Rhonda Fehring bought DTE Performance, a Corvette performance speed shop.

A few months into ownership, there was a transition of it being Corvette only performance into street car performance, focusing on ride development systems and components. John has been heavily involved in ride technology and development in past careers and consulting work in many of the main major shock systems on the market. His experience as Senior Project Engineer for Delphi Chassis gave him the ability to work with all ride controls products; shock designs, algorithm development, ride tuning & system integration. We are applying that to the business today.

In December of 2014 we purchased a Pronello Shock Dynamometer and became their North American dealer for Pronello systems. Developed by a racing family of engineers in Argentina, the Pronello design has zero lash system unique to Scotch-yoke shock dynos. The system also has the ability to run out in the 35 in/sec range compared to the typical 12 in/sec of other models and is ready to service all forms of suspension systems. We also corner weight and scale to racing specs needed to get the optimum performance out of suspension.
