IMSA

Parallel Lines - 1973 index


Again, the 1973 IMSA series consisted of 10 races, three of them at Daytona, and including a double-header at Lime Rock. Most races now had a 2-heat 100 mile format, aggregate placings deciding the overall results.

A new car entered the arena: The Porsche Carrera RSR. It would dominate the series for the next few years, but it dominated 1973 from race one. The championship was decided at the very last race of the season - it would be Gregg or Keyser, both with Carrera's. And this last race was won by Gregg!
