History of the Henninger RSR
Chassis number 911 560 9123 is registered as a 1975 911 Carrera IROC RSR, thought to be one of the last RSRS made by the factory – no other examples have been documented with later VINS.
According to Porsche records the car was sold in January 1975 to a New York dealer. Finished in Grand Prix Weiss (R4 code) and delivered in race trim (code M491), it was then owned and raced by Ludwig Heimrath, a Canadian racing driver with German origins. As far as the historical inquiry goes, Mr Heimrath worked at the Porsche factory before leaving the country for Canada. Heimrath raced this car in the 1975 Camel GT series with considerable success. Heimrath was supported by the German beer maker, Henninger, which is the livery the car sports today.
After a crash at the end of 1975 the original shell – minus engine and gearbox – was sent back to the factory for repair.
The factory also sent a replacement chassis (006-0024), which was raced with the original engine and gearbox from 9123 until 1977. Chassis 9123 was eventually sent back to Heimrath, but as he was busy racing in the replacement RSR, the chassis was sold in 1980, going on to trade hands several times until 1988, by which time the rolling chassis was found in weeds outside a workshop and in need of restoration.
With the restoration and mechanical build completed in January 1991, the car went racing once again, winning races in the Porsche Club of America racing series. The car was raced until 1996, at which time the owner retired from driving and the car was placed in storage until restoration in 2004. Its owner at the time, Gary Quast, tracked down the original engine and gearbox and installed it into the car.
In 2004 the car came to Europe, residing in Brussels, where it stays today. Displayed for almost a year in the Porsche Museum in 2013, the car has also been raced all over Europe and is maintained by 911 Motorsport, a leading historic car maintenance concern.
