What are the parts of the HPS suspension?
|
|
The HPS air suspension consists, like a conventional system, of springs and shock absorbers, though these have been specially developed for the airride technology.
The construction differs from model to model and depends on the requirements or the desired adjustment of the suspension.
The HPS Airride System also contains springs and a shock absorber, but a pneumatic spring, not a leaf spring, torsion bar or coil spring.
The pneumatic spring is filled with air. By varying the air pressure in the pneumatic spring, the driving height of the vehicle can be individually adjusted.
The air pressure change in the pneumatic springs is either performed by the air management system, or manually, as with a tire valve.
The air supply provided by the air management system has nothing to do with the composition of the suspension.

What are the parts of the Air Management System?
|
|
This depends on the upgrade level of the system. The main components of a fully upgraded system are compressor, air tank or reservoir, control valves, tubes, cables, sensors and switches. In the lowest upgrade level tank and compressor are absent. In this case, the air regulation is done manually via tire valves. |
|
|
|
| How many upgrade levels are there for HPS suspensions? |
|
There are basically the suspension components (shock absorbers and springs) and the air management system.
There are already various options for the suspension components. Usually, one buys a complete set of springs and shock absorbers. With some vehicles, it is advantageous just to replace the standard springs by special HPS pneumatic spring elements – the most cost-effective path towards the airride class.
In selecting the air management, there are virtually infinite options, with and without tanks, compressors, etc.
An authorized HPS dealer will help you find out more about how you can modify your vehicle.

|
|
| Which parts do I need? |
|
That depends generally on the upgrade level of the selected suspension and the air management system.
To drive with an airride suspension, only the HPS suspension components are needed.
To lower and raise the vehicle within fractions of a second by the push of a button you will need: compressor, air tank or reservoir, control valves, tubes, cables, various sensors and switches, and the HPS suspension components.

|
|
| How much does an HPS performance suspension cost? |
|
This depends on the upgrade level, your wishes, ideas and of course your budget, and ranges from Euro 600 (approximately $725) to Euro 20,000 (approximately $24,500).
|
|
|
|
| How much does the installation of an HPS Airride System cost? |
|
This depends on the size of the system and customer's individual wishes, covering everything from about Euro 500 ($605) to Euro 20,000 (approximately $24,500). |
|
|
|
| How long does the installation of an HPS Airride System take? |
|
The duration of the installation also depends on the size and complexity of the system. A smaller system can be installed in approximately 6 hours. |
|
|
|
| How much space do the components of the HPS Air Management System require? |
|
An average system can be placed in the space intended for the spare tire. This preserves the space in the trunk. It can also be installed below the car.
|
|
|
|
| How low can I lower the vehicle by using the HPS Airride System? |
|
The vertical movement zone is usually around 6 inches. Where you place this vertical movement zone depends on your wishes, legal requirements and the features of your vehicle.
In most cases, somewhat lower than a conventional performance suspension – but only in the parking position.
|
|
|
|
| How high can I lift the vehicle by using the HPS Airride System? |
|
Usually about 4-6 inches |
|
|
|
| How is the ride of the HPS suspension tuned? |
|
The suspension can be adjusted according to the customer's wishes. Anything is possible, from comfortable to extreme.
Usually, a sporty ride is desired, but with the comfort of the original setting. |
|
|
|
How fast can I drive with an HPS Airride System?
|
|
As fast as your car will go! There are no limitations compared to the original setting. |
|
|
|
| Are there any limitations for everyday use? |
|
No, none.
|
|
|
|
| How much spring displacement does the vehicle offer with the highest ground clearance? |
|
6 inches downwards. If you are already driving lower, usually
2-3 inches.
|
|
|
|
| Is the hardness of the HPS suspension dependent on the chosen ground clearance? |
|
Yes, though there are small differences in hardness according to the adjustment. |
|
|
|
Does the HPS suspension move to a preset position with the push of a button, or does the desired ground clearance have to be adjusted manually?
|
|
This is possible, if you want it.
The driving height is adjusted by a rocker switch, similar to a power window switch.
You adjust the driving height yourself, but have to keep it within legal limits.
|
|
|
|
| Is the ground clearance independent of the vehicle's load condition, or does the suspension air pressure have to be adjusted in order to maintain the ground clearance? |
|
Normally, the ground clearance of the vehicle is reduced when you load it, but it can be restored by additional pumping.
|
|
|
|
| Are camber and track changed by modifying the ground clearance? |
|
Of course. This is why a standard driving height is set during the installation of the suspension, which is supposed to be predominantly used. Camber and track are set for this height. You may only drive briefly on a height different from the standard one. |
|
|
|
| Can I drive for a long time with different ground clearances without causing excessive tire wear? |
|
Depends on your driving style. Slow driving during a show ("Cruising") is possible.
Long-time, long-distance, and fast driving at very different heights is not possible.
The camber and track of the suspension are set to a standard value after installation, which is supposed to be predominantly used.
You also have to stay within legal limits.
|
|
|
|
| How loud is the compressor of the airride system (inside and outside)? |
|
That depends on the installation location, but usually, it is not very loud. Mostly, it does not disturb anyone.
After all, the compressor only runs briefly to fill the air tank, i.e. when the tank's operating pressure falls below a preset minimum value.
