911 Carrera RSR 3.8 (964)

Why it matters

The 964 Carrera RSR 3.8 was Porsche’s lightweight, Turbo-bodied customer racing car for European Pro GT racing and the North American Supercar Series. It was based on the Carrera RS 3.8 and was a winner from the outset.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Body shells were built on the normal 964 assembly line with all seams welded, then sent to Matter for a triangulated roll cage before completion at Zuffenhausen. The car had a 3.8-litre air-cooled flat-six, individual throttle butterflies, twin ignition and Bosch fuel injection.

Factory records cited by RM Sotheby’s show 49 cars delivered, plus one pre-production test car and one factory race car. Four more were built in autumn 1994, which gave 55 and satisfied FIA homologation.

Identification guide

How to tell an original from a replica or later conversion.

The RSR 3.8 has a 964 Turbo-style wide body, light-alloy doors and front lid, a steel engine cover strong enough to carry the large fibreglass rear wing, lightweight bumpers and thinner side and rear glass. It has 18-inch three-piece centre-lock Speedline wheels, a front strut brace, a large nose-mounted oil radiator and a single Recaro seat with six-point harness. Chassis and options are documented in Jürgen Barth’s book on the 964 Carrera RS 3.8.
