> Exclusiv HiLOW â€“ The Individual Coilover!
These are the major advantages of the LOWTEC HiLOW system compared to conventional coilovers:
With the HiLOW coilovers LOWTEC has revolutionized the sport suspension market. All HiLOW series combine great race technique with premium products at a fair price.
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 TÃœV-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.
> LOWTEC Coil+Spring-Kit
If the electronic original damper system is to be retain on vehicles, the LOWTEC spring kit with threaded sleeves is the optimum solution for individual lowering.
The special springs are matched to the strongest adjusting of the original dampers. So the performance is comparable to the original sport suspension at the sportiest setting. Threaded sleeves are adapted to the top of the original shock absorbers. In conjunction with the attached LOWTEC spring cup the height of the car is individually stepless adjustable.

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.

Here is an overview of different suspension adjustments, based on various configurations in an average car:
|Type of Suspension||Spring||Damper|
|Original standard suspension||20||70|
|LOWTEC Sport suspension||30||110|
|LOWTEC Coilover DYNAMIC||40||130|

Rates in N/mm.
For light or heavy vehicles different values apply.
Already the TÃœV-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.
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.
> 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 (â€šblockedâ€˜), 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
