CSRG at 50

The Classic Sports Racing Group is celebrating its 50th season of racing. The David Love Memorial Races at Sonoma Raceway featured the usual assortment of open wheel and sports cars from the 50s to the 80s. 

I confess a certain degree of partiality for open wheel cars from the 1960s and 1970s. CSRG owners include a brace of cars from Formula Atlantic, Formula Jr, Formula Ford, and SCCA B-spec.  The earlier cars are beautiful silhouettes designed for slip stream racing of the era. 

Aero had entered the picture by the 1970s. Two of the Atlantic cars were raced by F1 champion Keke Rosberg and stalwart Didier Pironi. These lurid cars were prepped by Fred Opert and sponsored by condom company Excita. 
In the same vein, some of the Lola sports cars from the early 1970s are also fantastic, racy and properly noisy.
