Tuning upgrades for Audi A6 and S6 (C8 / 4K)

Not everyone drives an RS6 – but with the right upgrades, your A6 or S6 can come very close to that ideal. At GG2 Fahrzeugtechnik, we specialize in refining the C8 platform, particularly for the S6 TDI and the powerful A6 engines.

Our bestsellers for A6 & S6:

  • Sound & Active Sound (Especially for S6 TDI):
    The S6 C8 is often sold as a diesel in Europe. The sound? Subdued. With our Active Sound Modules (sound boosters) or a Active Sound Unit, you can give the V6 TDI a rich, full-bodied V8 sound. Individually adjustable via app and Drive Select.
  • Air suspension & lowering:
    Many A6 and S6 models are equipped with "Adaptive Air Suspension." Our Active Suspension Control module allows you to lower the vehicle continuously. This lets you achieve the perfect look when stationary, without sacrificing ride comfort. Alternatively, we offer KW coilover suspension kits (V3) for vehicles with steel suspension.
  • Optics & RS style:
    Sharpen the design. With black honeycomb grilles (RS look) , front spoilers and diffusers from Maxton Design , your A6 will look significantly more aggressive.
  • Wheels & Performance:
    Replace the standard wheels with high-quality 21- or 22-inch forged wheels . Performance upgrades from DTE Systems provide increased acceleration, which particularly unleash their full potential with TDI engines.
