This video captures a lap in a Porsche 964RS at Gotland Ring on July 17, 2023. This was one of the initial test laps following an engine rebuild and an RSR-style cooler update. The ambient temperature was 19 degrees Celsius, and the oil temperature remained stable at 73 degrees Celsius after a 7.3 km cooling lap. The car was running on Toyo R888R tires (225/255 17”), which the driver noted were not as effective as the Yokohama A052s, specifically disliking their stiff sidewalls.
