Celebrate the 50th anniversary of the IMSA RS series at Lime Rock Historic Festival

In 1971, a new racing series appeared. Its grids were filled not with high-horsepower track machines, but with sporty economy sedans popular with the consumer market from brands like BMW, Datsun, Opel and even AMC.

Called IMSA RS, the series continued through the ‘70s before being replaced by the Showroom Stock series in the mid-'80s.

One of the ]factors that made the series popular was the limit on how much cars could be modified. This kept IMSA RS not only accessible, but also very competitive.

Now, 50 years later, the son of late prominent IMSA RS driver Jerry Walsh, Brian Walsh, is organizing a celebration of the series–the IMSA RS 50th Anniversary Reunion–set to be a part of the Historic Festival 39 at Lime Rock Park, Connecticut, September 3-6.

Brian, who still campaigns his father’s Ford Pinto race car in a number of historic series, hopes to attract “50 or 60 cars, which was the size of the fields during the series’ most popular years from 1973 to 1979.”

The event is open to similarly prepared SCCA 2.5-Liter Trans Am and B/Sedan cars as well.

And the cars just have that coolness--the right stance from humble roots.
