(E) Tuning G-Power




  • G-POWER Bodywork

    G-POWER body parts not only improve aerodynamics but also offer a sporting and elegant appearance of your car.
    Available for all models, the bodywork programm is subdivided into two design lines.
    On one hand to emphasize the styling of the BMW series, on the other hand to give your BMW an individual appearance.
    The fastening will be carried out – according to standard – on all mounting points and is made of lightweight materials as Kevlar or GFG, providing the possibility of easy repairing at small damages.

    Carbon fibre (weight advantage of approx. 25 - 30 kg)
    (Assembly-time ~ 2 hours)


  • [COLOR="Navy"]G-POWER Braking system[/COLOR]


    It is not only the performance which is important – especially at high speeds achieved by G-POWER EVO III engines - a high decelaration is required.
    The G-POWER braking systems are especially developed according to the car type and have been tested on the “Nürburgring” race track.
    A great problem at braking is the “fading” (knocking in the steering wheel).
    In order to avoid this problem, larger brake discs with special saddles and brake pads were developed for the front axcle, as well as special brake fluids.
    According to the car model G-POWER supplies a front and rear axle system consisting of brake discs, brake saddles, special brake pads, Stahlflex brake hoses as well as brake fluid.


    G-POWER sport brake system GP1V, front axle
    4-pot Brembo brake saddle with 2-piece perforated brake disc, dimension 380 / 32 mm, incl. Stahlflex hoses and brake disc chamber, BMW E31 8series models starting at 90 tracking dist. 17 mm, *tracking distance = required braking distance between braking saddle and rim. Min. 19. Depending on wheel type, a track widening might be necessary.

    (Assembly-time ~ 4 hours)



  • [COLOR="Navy"]G-POWER Clutch (amplified)[/COLOR]

    Particularly for supercharged cars (as the G-POWER compressor cars EVO II and EVO III), G-POWER offers for these high requirements a particular clutch basing on parts of Fichtel & Sachs - meeting with the special requirements of today’s sport engines.
    The amplified clutch of G-POWER is made exactly for customers who want to keep their habits in operating the clutch as they are used to with the series version.
    For these customers we offer the GPS clutch sets, consisting of three pieces.
    The advantage of this clutch is that the rubbing discs, consisting of organic materials, are able to keep the pedal pressure despite of higher pressure on the clutch plate.
    These clutches can be used for performance upgraded cars (performance upgrade until 40 %).
    The GPR clutch sets are especially for supercharged cars, offering them a bit more pedal pressure and being designed for performance increases until 80 per cent. Special models on request.


    G-POWER clutch set GP R - E31 850i/850Ci/850Csi amplified
    Consisting of pressure plate (with changed pressure features), amplified racing clutch disc and corresp. bearings, e.g. for EVO II kits.
    (Assembly-time ~ 5 hours)


    G-POWER clutch set GP S - E31 840i amplified
    Consisting of pressure plate, amplified clutch disc and corresp. bearings, e.g. for EVO kits.
    (Assembly-time ~ 5 hours)



  • [COLOR="Navy"]G-POWER Compressor engines[/COLOR]

    The G-POWER compressor engines are the principal items of our developments.
    Since 1994 G-POWER has been market leading, e. g. in the area of compressors for the M3-engine, and meanwhile is offering for every 6- and 8-cylinder-engine an economical, practical concept.
    At the EVO II grades the conversion is done on the standard series engine with a maximum loading pressure of 0.35 thru 0.45 bars (depending on the engine type).
    The EVO grades II and III have to be installed in our workshop including the modification of the engine, according to car type.
    Due to the extensive experience of the last years, G-POWER offers you one year of guarantee on the conversion of a new car without any limit on the driven kilometers.
    The servicing as well as all other controls can furthermore be carried out by your BMW-partner.

    If the temperature rises to more than 100 degrees the additional cooling switches on, in order to avoid the wear and tear of the gearbox.
    These sets are available especially for differential cooling and transmission cooling (see car list).

  • [COLOR="Navy"]G-POWER Suspension [/COLOR]
    Especially regarding the sport suspensions the correct set up is one of the most important features.
    The G-POWER sport suspensions are developed and tested under conditions similar to races.
    The lowering by 40 mm’s, e.g. for an G-3 suspension kit, is sporty and taut, but still offers by the large remaining spring movement enough suitability for everyday’ s use particularly for very enthusiastic drivers.
    Due to the short spring movement remaining, 60 mm suspensions have a sporty, taut set-up.
    Especially for customers with high lowering rates with enough spring movement remaining and therefore a very comfortable adjustment, G-POWER offers the RS-spring strut suspension (also see in the product overview under lowering and adjustable suspension.)
