When it comes to the 911, ask any 'Porschephile' for their opinion as to which was the greatest racing 911 ever built and quickly you will become used to hearing the acronym 'RSR'. Introduced in 1973 by the factory as an evolution of the already potent 2.7 RS, it was both an official 'works' team car built to contest International World Championship 'Group' 4 GT endurance events and was also available for privateer race teams in full competition trim.

The 'RS' itself was a hugely successful development of the standard 2.4-litre flat-six. The engine was bored out to 2.7 and carefully massaged to produce 210 horsepower which was fed through a five-speed gearbox with uprated 4th and 5th cogs, all contributing to a top speed of over 150 mph. Revised and stiffened suspension and larger four-wheel disc brakes complemented the increased power and ensured the RS remained perfectly balanced. An initial order of 500 RS' was produced to meet FIA 'Homologation Requirements' but the cars were so popular that production eventually totalled some 1,580 units.

The most hardcore, no-nonsense, version of these race-focused 911s was the RSR. These Rennsport specials, with their dramatic, pumped-out wheel arches, intensified the standard 2.7 RS flavour in every way. Even wider, lighter, faster, and more capable in every performance category, the RSR was the RS unrestricted, dialled in for maximum capability with scant regard for creature comforts. The formula was successful – the 2.8 RSR is still recognised today as one of Porsche’s most successful race cars.

Sadly, however, if the RSR was in the 'Periodic Table of Elements, it would be 'Unobtanium' as just 49 were built resulting in them rarely coming to market, and when they do, the numbers are not for the faint-hearted. Consequently, anyone wishing to experience the addictive blend of handling, balance, performance, feel and simple purity that is the RSR, has no choice but to create their own.
