CarBahn Motorsports announced today its entry into the IMSA Continental Tire SportsCar Challenge with the Audi R8 LMS GT4, as a new project led by motorsports veteran Steve Dinan.

Jeff Westphal, Tyler McQuarrie, Mark Siegel and Sameer Gandhi will be campaigning the team’s Audi GT4 car.

Dinan is no stranger to motorsports, after owning Dinan Engineering, an aftermarket BMW tuner from 1979-2013.

Dinan was an engine supplier to BMW race teams around the world with many class victories and several championships, including partnering with BMW and Chip Ganassi Racing, where they won the Rolex 24 in 2011 and 2013, along with Daytona Prototype driver’s championships in 2010, 2011 and 2012.

“I’m excited about having a team again and we’re happy to be campaigning an Audi, said Dinan. We think their new R8 GT4 will be very competitive.

“We are lucky to have great sponsors like Accel Partners and Menlo Ventures and fantastic lineup of drivers. We’re looking forward to a successful season.”

Steve’s new company, CarBahn Autoworks is a chain of repair facilities and high-performance modifications on Audi, BMW, Mercedes and Porsche.
