In August 2023, the Cup vehicle underwent a major service. Among other things, a pressure loss test was carried out during the engine inspection with positive results, the spring plates were replaced with racing spring plates as a precaution (there was a recall by Porsche in the early 90s) and the valves were adjusted. All fluids such as engine oil with filter, transmission oil, and brake fluid were changed, spark plugs were replaced, the distributor cap and finger were replaced, and the axle geometry was measured and adjusted to the 18-inch wheels, with settings selected for track days.
November 2024: Clutch completely replaced with flywheel, sintered drive plate, release fork, release bearing, pressure plate, and minor additional work such as replacement of the engine oil seal. Invoice amount: €4,462.00.
The original old vehicle registration document is available.
The vehicle has 8 tires; the photos show the 18-inch RH Speedline rims.
The vehicle also has the original one-piece Cup rims, 8×17 ET 52 at the front and 9.5×17 ET 68 at the rear.
A real rarity – 964 Carrera Cup vehicle partially in its original paintwork and without Cup racing use in complete original condition.
Matching numbers – engine, transmission, and all body parts.
1991 (ZMS 409XXX) vehicle with road registration.
All logbooks and the original service booklet are available, but there is no vehicle registration document.
One of the milestones in the model history of the 911 Type 964 is undoubtedly the Cup version M001 for the fastest one-make cup in the world.
Cup 964s from the first four years, in which 360 units were produced, have become rare and are sought after by collectors looking for exclusivity.
The previous owner of this vehicle, who is active in historic motorsport, also recognized this when he discovered an untouched example in the Lake Constance region, which was delivered to Italy in 1991 as a reserve car for a Porsche Cup team and then immediately passed on to a private owner.
The mint condition of the car suggests that it has never been used. Accordingly, no entries can be found in the records.
At the end of 2007, the 964 Cup was deregistered and stored in the collection.
