Gran Tourismo Racing ClubSport

The 911 GTR CS is based on our RennSport model 911 Carrera RS and our Beauty Beast 911 BB, but goes even a step further.

Exterior options
As usual, we offer exterior parts made out of Pure Carbon™ and our Carbon Hemp™ for the:

  • roof,
  • fenders,
  • doors,
  • bonnets,
  • bumpers,
  • diffusor,
  • wings,
  • rims, and
  • other exterior parts,

    and polycarbonate for the:

  • rear window and
  • side windows,

    besides lightweight components as the:

  • racing windscreen made out of a thinner laminated safety glass,
  • racing headlights, and
  • quick release fasteners for the hoods.

    Interior options
    Carbon Hemp™ is also used for the fabricating of the:

  • seats and
  • dashboard,

    while we are also offering as performance options:

  • steering wheels,
  • anti-noise system for cancelling all kinds of noise,
  • racing accumulator,
  • racing equipement, and
  • other interior parts.

    Drivetrain options
    Furthermore, we replaced the boxer engine with a 2.8 to 3.0-liter 75° 32 valve V8 engine based on the motorcycle engine of the model Hayabusa by the manufacturer Suzuki, or in the future with our own 90° engine with a similar specification. Due to the small dimensions of the drivetrain it can be mounted transversely, or as a midengine resulting in a highly optimized weight distribution. Further optimizat- ions of the drivetrain are achievable with the:

  • Active Transmission™ based on our Modular Transmission™ System and featuring:
    • 6 or 7 speed,
    • sequential race gearbox,
    • independent shifting rods with single clutch or
    • dual clutch,
  • high-performance titanium or Inconel® exhaust system, as well as
  • carbon carbon or ceramic composite brake system.
