It was 45 years ago on February 1-2, 1975 that IMSA began sanctioning the 24 Hours of Daytona, an event that Bill France Sr. had built into international prominence starting in 1962 with a 3-hour Daytona Continental. With excerpts from "IMSA 1969-1989," Mitch Bishop recalls the 1975 event and how it propelled Peter Gregg and Hurley Haywood to stardom.

Much of the development of the now-iconic Porsche 917 was conducted in secret before running its first few races in 1969. What was not a secret was the car had significant handling issues, especially at high speed. Porsche engineers worked on the issue throughout the 1969 season, but it was a hunch and a bit of aerodynamic patchwork that solved the problem. In this post from noted Porsche 917 author Jay Gillotti, he recounts the top-secret test at the end of 1969 at Daytona that would ultimately determine the fate of the 917.

The 24 Hours of Daytona is one of the most prestigious sports car endurance races on the international racing calendar today. But it wasn't always run as a "once around the clock" event.

In this excerpt from the recently released book on the development of the Hans device, Jonathan Ingram tells the story of Jim Downing's awakening to the dangers of frontal impact in race cars.

Here are some rare photos from the IMSA collection at the IMRRC that document the day.
