First used in the fabrication of the legendary 1973 RSR 2.8.
An option to the standard Carrera, the 491 code was probably the most comprehensive and certainly the most expensive, Porsche keen to offer the wider and more agressive looking Turbo aesthetics.
Slightly slower and 70kgs heavier than a standard Carrera, but more drivable than a Turbo ...
123mm wider, standard body with wide front and rear wings, shaped bumpers, wrapround chin spoiler and Turbo rear wing.
Derived from the 917 racing program, cross drilled front and rear discs with 4-piston aluminium callipers.
To match 911 Turbo, larger front torsion bars and anti-roll bar, larger rear torsion bars and semi-trailing arms.
