MacNeil, Lietz, Estre and Bruni for Rolex 24

Fort Lauderdale, Fla. (Jan. 6, 2021) - WeatherTech Racing will move up to the IMSA WeatherTech SportsCar Championship GTLM Class with Porsche and Proton Competition for the 2021 season.


Cooper MacNeil (Hindsdale, Ill.) will be joined by Richard Lietz (Austria), Kevin Estre (France) and Gianmaria Bruni (Italy) for the Rolex 24 At Daytona.


The team that started in sportscar competition in 2012 in the American Le Mans Series, winning the GTC Championship in 2012 and 2013, will move up to IMSA’s premier GT class by entering their No. 79 WeatherTech Racing Porsche 911 RSR in the GTLM Class starting with the Rolex 24 Hour At Daytona in three weeks.

Proton Competition will make the move to full-time racing in North America in 2021. The team has competed in the WEC as well as the European Le Mans Series and is adding the IMSA WeatherTech Championship this year. The agreement will also see the team apply for an entry in the 24 Hours of Le Mans in the GTE Pro Class.


“We have put a lot of thought into this move,” MacNeil said. “I have raced against this level of competition at Le Mans twice, most recently this year, and have felt comfortable with the added performance of the car. We are going back to running a Porsche, and I am looking forward to getting behind the wheel of the 911 RSR. It will be more pressure on me as a driver, but I am welcoming the added effort it is going to take to run GTLM in 2021.


“We raced with Christian at Le Mans in 2016, so we have an on-track history. I am looking forward to running the Rolex 24 with Richard, Kevin and Gimmi. Proton has a great endurance racing history, and Porsche is always competitive at Daytona.”

For Christian Ried, Proton Competition owner, it will be his first full season of racing in North America’s premier sportscar series.


“We have been looking at entering the IMSA WeatherTech Championship for a few years,” Ried explained. “We just didn’t feel like the time was right until now. With the factory effort leaving, that left a void for Porsche in GTLM. We were able to get together with David and Cooper [MacNeil] to keep the Porsche brand racing at the top level of GT competition in IMSA. I am looking forward to the challenge and am excited to add IMSA to our racing schedule in 2021.”


The 2021 IMSA WeatherTech SportsCar Championship season will start with the traditional Roar Before the 24 test at Daytona International Speedway, January 22-24. The Rolex 24 At Daytona will run January 27-31.
