Sixteen (16) Porsches come to Sebring, Florida for IMSA’s open test at Sebring International Raceway on February 20 – 23. Testing on the bumpy 17-turn track has been ongoing for many teams but this is the first official IMSA-sanctioned test for all these classes in preparation for the March 17 Mobil 1 Twelve Hours of Sebring. The Porsche GT Team has entered both factory 911 RSRs in the WeatherTech SportsCar Championship GTLM class for the test.
