For race teams and track day customers Porsche prepared a small number of the 964 Cup cars according to the FIA NG-T regulations. Officially called the Competition model, these custom-ordered cars were an intermediary step between the Carrera Cup option (M001) and the standard tourer (M002). This M0003 option was available directly from Porsche as a road-going model.
These cars had almost all the Carrera Cup modifications including the new suspension. This lowered the car by 40mm in the rear and 50mm in the front. It also included fitting of the larger 930 Turbo disc brakes and adjustable anti-roll bars. The same weight reducing measures included thinner windows, stripped interior, aluminum panels and Recaro racing seats which helped lower the bulk by 200kg.
Mechanical preparation included a specially-built engine with a new intake manifold, lighter fly-wheel and larger air filter. In the suspension all the rubber elements were replaced with rigid ball-joints. Similarly, uprated Bilstein shock-absorbers were fitted.
Accoring to 964 expert Bob Gagnon, the M0003 competition car included the following modifications:
*Deletion of interior carpeting, headliner and A/B pillar covering.
*Painting of interior to match exterior colour.
* Shortened knee padding on lower dashboard to clear roll bar installation if ordered.
*Driver’s side sun visor only.
*Provision to unlock trunk and fuel door from drivers seat
*Engine compartment insulation deleted
*Six point seat belt for driver and passenger.
*DME Brain box moved behind drivers seat (standard location under seats in way of crotch belts mounts).
*Hand held fire extinguisher mounted on passenger floor.
*Cable activated master switch from inside of car
*Recaro SPG bucket seats for passenger and driver.
