Electronic damper lowering
Adjustable and speed-controlled electronic suspension lowering kit. The stock adjustment possibilities are retained, but all levels are lowered by the defined value. We recommend a lowering by
- 30mm at the front and 20mm at the rear axle for regular cars and
- 40mm at the front and 30mm at the rear axle for SUV
The suspension can be adjusted independently for each axle. To retain the comfort of the stock suspension, the lowering kit will disable itself at a speed of about 70km/h. No alignment of the axles necessary. No increase in tire wearout.

Sport Brakes
Improved brake retardation through 6-piston-technique. Ventilated, perforated and slotted sport-braking-discs
- Front: 6-piston-calipers, 360mm x 36mm
- Rear: 4-piston-calipers, 330mm x 26mm
- Front: 6-piston-calipers, 360mm x 36mm
- Rear: 4-piston-calipers, 330mm x 26mm
Raise of top speed
Manufactures often limit the top speed of their cars electronically. It is possible to raise this limit. Approved tires and a matching speedometer are mandatory. This service is already included in all electronic performance improvements.
Codings
We can deactivate or modify unwanted software features. It is also necessary to activate electronic parts that have been installed subsequently.
These features include i.a. :
- Deactivation of Start/Stop-ECO-Mode
Protect your engine and starter. Without the Start/Stop functionality, you alone decide when the engine turns off.
- Deactivation of acoustic seat belt reminders
No annoying alert if you don't want to buckle up or put some weight on the passengers seat.
- Custom adaptions
If you have a special request, please use our contact form.
Send us all the details of your endeavor and please include your VIN and/or parts number.

AMG Instrument Cluster
Upgrade your instrument cluster to the AMG version of your vehicle class. The advantages are an extended speed range, availability of the AMG-Menu and the AMG start screen.
Retrofitting
Coding and installation of new hardware - After the installation of various hardware components, like a tow hitch, facelift or AMG parts, these components also have to be electronically coded into the vehicle. We can perform the installation of hard- and software for you.
Brakes with compound technique
Improved brake retardation and weight-reduced through compound technique with aluminium rotor hat.
- Front: 6-piston-calipers, 390mm x 36mm
- Rear: 4-piston-calipers, 360mm x 36mm
- Front: 6-piston-calipers, 390mm x 36mm
- Rear: 4-piston-calipers, 360mm x 36mm
Exhaust system: Sound
Improve the sound of your car through our stainless steel exhaust systems, consisting of center and rear exhaust in the versions "TÜV" and "export". They impress with high quality, design and sound.
Carbon / Ceramic Brakes
Maximum braking force, less weight and wearout. Brake retardation like a racing car, short brake path, precise pressure point, maximum stability. Tolerant against extreme stresses and heat, no corrosion, little wearout, almost no loss in braking power. Improved driving dynamics thanks to about 40% weight reduction, less unsprung mass, more performance. Ventilated and perforated Carbon/Ceramic-compound disks.
- Front: 6-piston-aluminium-fixed-calipers: 402 x 39 mm
- Rear: 4-piston-ceramic-fixed-calipers: 360 x 32 mm
- Front: 6-piston-aluminium-fixed-calipers: 402 x 39 mm
- Rear: 4-piston-ceramic-fixed-calipers: 360 x 32 mm
Chassis components
For the perfect tuning of the handling, we are happy to check the availability of various components for your individual vehicle on request.
Such components may include, but are not limited to:
- Racing Anti-Roll-Bars
Due to the use of more durable anti-roll-bars, you get a better handling and you can drive higher speeds on curves.
- Wheel spacers
This allows negative fine tuning of the
offset of your rims without replacing them.
- Adjustable aluminum top mounts
The ability to perfectly tune the suspension geometry can be obtained by installing our adjustable top mounts. Despite a lower suspension setting you can adjust the suspension geometry to the requirements of the tires and your intended use.
The availability of the respective components depends on the individual vehicle model. We will be happy to provide you with precise, individual information for your vehicle on request. Please also include the chassis number. This list does not represent a statement about the possible availability of the components shown and only serves as a basis for an individual inquiry. It is possible that no components are available for your vehicle.
