The dynamic performance of the HiLOW system is unique. Depending on the different tuned series it will offer racing feeling or a sporty rest comfort.

With the HiLOW coilover race technique is roadworthy!

Decisively different

In conventional coilovers the height of the vehicle can only be set with the lower spring plate and usually only in conjunction with a helper spring. With the innovative HiLOW adjustment system the vehicle height will be changed at the lower bracket. This has several advantages: Adjusting the height is greatly facilitated free of any spring pressure and helper springs can be dispensed with.
The preload and thus the spring travel can be changed separately according to individual needs. Depending on the preload the spring travel and the progressivity of the suspension can be reduced or enlarged controlled in functional conjunction with the special bump stops as an additional spring element.
The stepless height adjustment offers an unrivaled wide adjustment range for an individual vehicle appearance from heightening to extremely lowering.

Driving pleasure

Dynamic performance brings the adjustable and constant spring travel independently of the vehicle height. Since spring preload and spring travel are not affected during the height adjustment, the spring-damping characteristic remains always in the best effective range, no matter how high or low the vehicle is driven. The precise tuning of the shortened stroke with the spring system optimizes the riding characteristics in addition.

Detail & Design

The certified and completely self-developed module system is demountable in every detail and also interchangeable and upgradeable in every series. Elaborate workmanship, stable surface protection and anodized aluminum components give the HiLOW coilovers an attractive and high quality look.

Style & Performance

Whether threaded dampers of steel, stainless steel or with hardness adjustment, all models are equipped with the sporty twin tube gas pressure technology. And the interior, equipped only with top materials, fulfill maximum requirements, such as the latest piston technology with durable Teflon bearing surface, high temperature oil for stable working performance, hard chrome plated piston rods with optimized surface quality for best protection against external influences.
All the LOWTEC dampers are not only equipped with a limitation of the upward stroke (rebound), but with real piston rod shortening. Even in extreme lowering this ensure for spring preload and prevent the destructive touch of the piston rod on the bottom valve. Just like the rebound and compression force of the extremely stable special shock absorbers, the respective spring rates of the special springs are adapted to the different tuned series perfectly.
The special springs are manufactured exclusively in Germany/Western Europe and are optimised by complex manufacturing processes. This top quality is standard for each HiLOW kit!
Each coilover is built up in house by trained LOWTEC personnel in selected quality for maximum value and is subject to comprehensive quality control.
This all results in reliable and durable suspension systems without compromise.

subject to change

For the Motorsport series HiLOW 2M, HiLOW 3M and HiLOW 4M the specifically required springs will be chosen to the fitting dampers according to the motorsport purpose (manufacturer expertise on request).

HiLOW 4
with adjustable damping force

The very large and well definable adjusting range of the HiLOW 4 damper is unique and of great benefit. This set the individual configuration and effective suspension adjustments almost no limits.
With the selectable types of springs DYNAMIC, STREET, RACE and MOTORSPORT the vehicle can be tuned in everyones particular driving style and needs by choosing the best matching adjustment of the dampers, which adjusting range is from 100 to 300 resp. 400 N/mm in the rebound force, while the corresponding adapted compression force changes only on a small range.
All versions can be realized with one type of shock absorber, so that, if required, a significant modification of the suspension chassis and thus another intended use can be realized only with the replacement of the spring. The HiLOW 4 damper are engineered by LOWTEC and they are all handmade in house.

Suspension hardness in comparison

Here is an overview of different suspension adjustments, based on various configurations in an average car:

Type of suspension	spring	damper
Original suspension	20 N/mm	70 N/mm
Sport suspension kit	30 N/mm	110 N/mm
Coilover DYNAMIC	40 N/mm	130 N/mm
Coilover STREET	50 N/mm	160 N/mm
Coilover RACE	60 N/mm	190 N/mm
Coilover MOTORSPORT	more than 80 N/mm	more than 200 N/mm

For light or heavy vehicles different values apply.

MaxLOW

Already the approved lowering values allow very low settings. Often it is possible to get much more lowering away of the tested range. The description "MaxLow" shows the technically/theoretically possible lowering out of the tested range.

MegaLOW

With the MegaLOW special version the HiLOW system also provides the possibility to achieve extreme lowering, whether for racing or show area or in the public road traffic.
For this, we build your individual HiLOW coilover with special components. If desired, also the hardness of the suspension can be adapted by alternative springs and damper units (please inquire separately).
In the column MegaLOW the catalog/shop shows the technically / theoretically possible lowering with the changed components (special parts for more lowering on request). Interesting is, that the chassis suspension so still is fully roadworthy as with regular components, unlike other coilovers kits, where usually the springs travel and / or the limitier must be eliminated. With the system HiLOW the springs travel of the struts meet even the testing standards. Extremely lowering may cause negative effect on the ground clearance of the vehicle, the drive and suspension geometry, etc. and can be correspondingly limited by this vehicle technical factors in practice . It´s necessary to be proved in each case.
The individual production of a MegaLOW coilover kit we make in short term and at reasonable rate.
For the MegaLOW costum coilover a LOWTEC manufacturers declaration on the vehicle chassis number related to the particular components is available on request.

Height adjustment of a HiLOW strut

The vehicle height of the unique LOWTEC HiLOW coilover suspension system can be adjusted by turning the complete damping-spring unit in or out of the lower bracket. Contrary to standard coilover types the vehicle height will not be adjusted by turning the lower spring cup. The springs are preloaded ca. 0-30 mm according to the TÜV certificate („permissible range of adjustment for spring cup seat height“). In this pretended range the springs can be adjusted (max. preload = max. spring travel).

Brief Instruction

loosen the hex socket screw of the locking ring
release the locking ring from the bracket
spin the spring-damper unit up or down by hand or hook wrench as required
tighten the locking ring Further details can be found in the mounting instruction.

Helper Springs

The only purpose of helper springs is to keep the main spring under preload in the range between minimum and maximum lowering. When the lower spring seat is fully turned down at maximum lowering, the helper spring is under minimum pressure. At a higher setting of the suspension the pressure of common helper springs increases each 10 mm for at least 20 kg. When the spring is fully under pressure (‚blocked‘), 140 kg or more can weigh on the adjusting cup.
This makes adjustment much more difficult.
Helper springs with a rate of about 20 Nm/mm, as they are commonly used, do not influence the driving quality, since they are no longer effective.
Due to the basic weight of the vehicle, each spring of the front axle is loaded with at least 250 kg. Due to the blocking of the 20 Nm helper spring, which is already at approximately 140 kg, only the main spring will affect the suspension.
As the LOWTEC HiLOW coilover kits do not need any helper springs, adjustment is easily possible without any pressure on the spring

Motorsport & Custom (individual production)

The race technique of the HiLOW System is predestined for use in motorsport.
Moreover the HiLOW modular system is ideally for individual and custom-made production, whether for a type of vehicle which is not yet in our list, for a classic car or a special vehicle type.
With our many varieties of damper units and race springs we can implement appropriate adjustments to many vehicle types and applications.

Your request

For a first overview and quotation of custom made products for vehicle types that are not listed in our catalog/shop we usually need pictures or drawings of the installation situation and the measures of the damper -springs system, if data and dimensions are not fully available.
The individual production of a MOTORSPORT or CUSTOM coilover kit we realize in short term and at a reasonable rate.
