## History

The 964 of 1989 modernized the 911 with coil springs, ABS and all-wheel-drive options — and became the platform on which Porsche industrialized customer racing. The 1990 Carrera Cup Deutschland fielded identical 964 Cup cars, inventing the one-make formula every Supercup grid since has followed; the lightweight Carrera RS of 1992 spawned N/GT club-racing versions; and the wide-body 1993 Carrera RSR 3.8 crowned the line as a genuine GT racer.

Competition results followed the ladder's logic: Cup racing produced the era's German touring-car names, RS N/GTs filled national GT grids, and the RSR 3.8 won the GT class at Le Mans in 1994 (Larbre), took Interserie and ADAC GT honours, and gave the customer base a car that could genuinely race factory opposition.

The collector market has since sorted the family into clear tiers: genuine RSR 3.8s (55 built) sit above seven figures; Carrera RS 3.8s and documented Cup cars with period racing history climb steadily; standard RS models anchor the air-cooled boom. On the marketplace the 964's breadth — Cup car, RS, club racer, backdate donor — makes it one of the most searched historic 911 generations.

## Palmarès

Le Mans GT2 class winner 1994 (Carrera RSR 3.8, Larbre Compétition); Porsche Carrera Cup Deutschland champions 1990–1993 in 964 Cup cars; ADAC GT Cup and Interserie class wins; national GT and club championships across Europe with RS N/GT machinery — the record that validated Porsche's customer-ladder model.

## What to check before you buy

The Kardex and Porsche's build records sort the tiers ruthlessly: genuine RSR 3.8 (M64/04 engine, factory wide-body — all 55 documented), Carrera RS 3.8, RS N/GT with period logbooks, Cup cars (verify Cup-specific chassis numbers; many were converted to road or track use), then modified road 964s. Check for the generation's known issues — cylinder-head sealing on early engines, corrosion at the front boot floor — and on race cars insist on period entry-list evidence: 964 'RSR tributes' outnumber real ones many times over. Matching numbers matter less on honest club racers, completely on RS/RSR collectibles.

## Did you know

- The 1990 Carrera Cup was one-make racing's template: identical sealed cars, driver-swap prize tests — the formula Supercup still runs three decades later.
- Only 55 Carrera RSR 3.8s were built, each hand-finished at Weissach; period price was roughly double a road RS 3.8 — the gap today is several multiples.
- 964 Cup cars deemed obsolete in period were often converted back to road spec — reversing those conversions with documentation is now a specialist cottage industry.
