ANGLETON, Texas – This week, sports car sprint racing team EFFORT Racing heads to Detroit, Michigan for Rounds 10 & 11 of the Pirelli World Challenge. Joining the team for the double header will be Dutch driver Renger van der Zande. Van der Zande will replace Scotsman Ryan Dalziel in the #31 Porsche 911 GT3 R.

Dalziel, who currently sits second in the GT championship will miss the two Motor City rounds due to a previous commitment in Le Mans. Van der Zande will be pulling double duty, also competing in the TUDOR United SportsCar Championship.

“Renger is a well-known driver in sprint and endurance racing,” said EFFORT Racing Technical Director Stefan Pfeiffer. “I’ve worked together with him before, and with race winning results. He’s a great guy on and off the track.”

Between drivers Ryan Dalziel and Michael Lewis, EFFORT Racing has earned 10 podiums so far in the 2015 race season, which both drivers holding five each. After a successful start to the season in the GT Amateur class, American Porsche Young Driver Development racer Michael Lewis was moved up to the GT category, competing in the overall class.

“Between Pirelli World Challenge and The TUDOR Championship, I am on double duty in Detroit, which is something I’m very much looking forward to. It’s the best combined from the top USA endurance class and the top GT sprint class together, which is amazing. I want to thank EFFORT Racing for bringing me on board this successful team. The track will be new for me, but I will obviously have enough track time before it’s game on and we’re racing for the trophies.”
