Porsche 964 Cup

INTERIOR
With only one purpose in mind the interior of the Cup car is minimal; raw and very noisy! A huge amount of Porsche racing expertise went into the Carrera Cups to remove weight and build a genuine race car that could be bought direct from the manufacturer.

At the centre, and more obviously, a Recaro SPG race seat (passenger also currently in place) was fitted along with an alcantara race steering wheel. The A/C and radio was naturally removed along with sun visors, headlining, central locking, alarm, electric mirrors as well as any interior sound deadening and carpets. Driver and passenger headsets have been fitted which can be controlled by the once used heated rear window lever.

More subtly Porsche removed tabs in the body for mounting interior parts along with the petrol flap lever; replaced with a wire loop such was their commitment to weight loss.The car even has a bespoke lightweight wiring harness, fabric door pulls and panels, manual windows along with 3mm lightweight side and rear glass.

ENGINE & TRANSMISSION
The engines in the early Cup cars were all produced with 260 horsepower using the 3.6 litre M64/03 units. They were picked from the standard production line and specially balanced and blue printed then selected further for identical power. ECUs were reprogrammed for extra output utilising 98 octane fuel with the engine hot air blower removed and replaced with a plastic tube.

Still retaining its matching number engine, and fully rebuilt to the same exacting standard, it is coupled to a ’91 spec G50/10 five speed manual gearbox with competition gear ratios, steel synchros and matched together with a lightweight flywheel and sports clutch as well as LSD. Solid engine mounts and harder rubber transmission mounts reduced any unnecessary movement under the higher loads generated on the race track.

The chassis runs specially designed Bilstein “Cup” shocks exclusively designed for Porsche and the 964 Cup. These were combined with Eibach progressive rate springs, larger and adjustable anti roll bars along with stiffer control arm bushings and Cup specific strut bearings. Ride height was reduced and rear camber eccentrics allow for improved suspension geometry setup all of which make up its superb looks and supreme driving characteristics.

WHEELS, TYRES & BRAKES
Timeless Cup 1 wheels present in excellent condition wrapped in nearly new Michelin Pilot Sport Cup 2 rubber.

Cup cars were fitted with larger Turbo specification brake calipers and discs attached to aluminium front hubs to reduce weight. Discs, pads and black calipers remain in good condition and are subtly visible through the alloy wheels.
