Er staat carrera Rs onder de taartschep en als je met google zoekt naar plaatjes dan komen er een paar qua kleur velgen bandenmaat taartschep heel dicht in de buurt.
Een 964 Rs ziet er ook van buiten niet zo anders uit.
Van binnen heb je allen geen armleuningen meer en gen vloermatten en nog wat van dat soort gein om hem zo licht mogelijk te maken.

The 964 RS was designed to enable owners to use their car on the road, track, hillclimb or sprint.

The body shell was stronger and lighter too, with aluminium front lid, seam welding, lighter doors and 3mm versus 4.7mm side windows, lightweight rear bumper, underbody sealant deleted, an in built battery cut off switch, special ultra light Magnesium 17" Cup wheels, 40mm lower suspension and much uprated dampers and springs. Turbo front brakes brakes with re-tuned ABS.

The picture above right of a black 964 RS is of a one owner totally original 30,000km car. Note the different rear pu to the standard 964.

Inside you got lovely lightweight carbon fibre 'Recaro' race seats, 4 point safety harness, no air con, no heated window, no electric windows or central locking and special thin side glass..

Trim was sparse, very basic door cards, a little strap rather than a handle to pull the door shut, little soundproofing, the rear seats were removed -even the interior light was deleted in effort to save weight.

You could order your car with or without a roll cage, but only some small luxuries were available on the basic version, including optional leather covering for the seats.
