The Porsche 934 3.0 RSR was a race car that was first introduced in 1975.

The Porsche 934 3.0 RSR was also equipped with a number of other high-performance features. These included a five-speed manual transmission, a limited-slip differential, and four-piston brake calipers. The car also had a fully adjustable suspension system, which allowed drivers to fine-tune the handling characteristics to suit the specific demands of different racing circuits.

In terms of performance, the Porsche 934 3.0 RSR was a dominant force on the track. It won a number of races and championships in Europe and North America, including the 24 Hours of Le Mans in 1977. The car was also successful in endurance racing, owing to its reliability and durability.
