The three ST coilovers ST X, ST XA and ST XTA always allow the same stepless lowering within the context of the respective parts certificate. While the ST X does not have in rebound adjustable dampers, the ST XA and ST XTA coilovers feature dampers that can be set tighter or more comfortable with the integrated rebound adjustment. The adjustable dampers have a total of 16 click stages. In addition, the ST XTA front axle struts are always delivered with a two-stage racing sport spring system and aluminum top mounts. As far as it is possible due to the construction design, the top mounts of the XTA can be adjusted in camber and caster.

The ST and KW coilovers differ in quality and the used technologies, there are no congruent products. Most obvious is certainly the material used for the housings, which are KW-typically exclusively made of stainless steel or aluminum, while ST uses the common standard with galvanized steel housings. With the KW dampers exclusively used for ST, only the rebound damping forces of the ST XA and ST XTA can be set with 16 clicks.

All ST coilovers are manufactured directly at KW automotive in Fichtenberg (Germany).

Different single parts such as dampers, elastomer spring elements, struts, dust protection sleeves, springs, top mounts, etc. can be ordered directly via the spare parts service on the homepage.

All of our products set a very high standard in quality and durability. However, even with our products, a defect cannot be entirely ruled out. Should your purchased products have any defects, please contact us as follows:

Please send us an Email to [email protected] with your contact data (complete address including telephone number); Your customer number and/or invoice number; part number and product name; note, if repair or warranty (24 months after date of purchase); information about your car (manufacturer, model, type, engine, year of construction) and detailed description of your complaint.

Afterwards you will receive an Email from our support team with all further information.

The coilover suspension and the technical component report, installation documentation, spanner wrench for adjusting the lowering, mortise dial for adjusting the damping forces as well as the associated adjustment manual if the ST coilover suspension features adjustable damper.

Yes, the professional installation of the ST coilover suspension can be entered into the vehicle papers by a car expert due to the enclosed technical component report on the compliance of a vehicle with the intended installation of vehicle parts according to § 19 para. 3 No. 4 StVZO (German Road Traffic Registration Ordinance). An entry is necessary immediately after the installation of the ST coilover kit.

At any car master workshop - regardless if it is a free workshop, an authorized repair shop, a tire workshop or a certified KW / ST specialist dealer.

We always recommend the setting of the specified track and camber values of the respective vehicle manufacturer for your car.

Wheel hub is not like wheel hub. Numerous automobile manufacturers use different dimensions and bolt circle patterns for the wheel mounting. For this reason, we have developed a variety of spacer and attachment systems for a fast and safe assembly to provide track widenings for more than 90 percent of all registered vehicles.

Which wheel spacer system you need, depends mainly on the spacer width that you want to install. With our DZX wheel spacers (through hole system with multi-hole circle) for example you can achieve a track widening of 5 to 25 mm in precise 2,5 mm steps per wheel. For a track widening of 20 to 35 mm per wheel, our AZX screw-on system with hole circle bores is the ideal track widening for your vehicle. Both systems are suitable for vehicles with wheel bolts and wheel studs.

Due to many different wheel- / tire combinations that are possible for each vehicle, we generally recommend to measure the maximum possible track widening directly on the vehicle.

In addition to our wheel spacer finder, we also have a small checklist available on our ST homepage that will help you to find the perfect spacer width. You can also contact our wheel spacer specialists in your area https://www.st-suspensions.net/dealersearch or directly contact our colleagues from the sales department at +49 (0) 79719630-120.

If you decide to get spacers with a technical component report, an entry into the vehicle papers is necessary after mounting the wheel spacers. Thanks to the appropriate parts certificate, the vehicle expert checks the proper installation and enters the spacers into the vehicle documents.

Our ST wheel spacers feature a technical component report and thanks to the accompanying certificate on the compliance of a vehicle with the intended attachment or installation of vehicle parts in accordance with § 19 para 3 No. 4 StVZO (German Road Traffic Registration Ordinance), our ST wheel spacers can be registered by a vehicle expert in the vehicle documents. For some applications it is necessary to register by an individual approval in accordance with § 21 StVZO, where we will provide the appropriate strength report of the ST spacers.

You will find our ST wheel spacers in stores, at our wheel spacer experts and also directly on our homepage. Our wheel spacer finder helps you to quickly and easily select the right ST wheel spacers for your car.

If you configure the spacers for your car on the homepage, our wheel spacer finder always shows you which mounting material you will need for your desired track widening on your car.

Depending on the selected system, a set of ST wheel spacers contains:

2 spacers, matching adapter or hub centering rings, technical component report and installation instructions. At screw-on systems, also wheel bolts or wheel nuts are included for attaching the spacer to the wheel hub.

Otherwise, please do not forget: Always order the respective mounting material with your purchase.

Thanks to the conical shape and the high-strength composite material of our adapter rings, there is the advantage compared to conventional, mechanically produced aluminum wheel spacers that manufacturing tolerances of the wheel hub or rim can be compensated. So no vibrations can occur with our DZX and AZX wheel spacers and a perfect wheel hub centering with a perfect fit is achieved! Also, the ST centering rings cannot fall out when changing the rims and there is no corrosion at the wheel hub connecting area.

When getting lowering springs you have to decide already before the purchase, which lowering you would like to reach. But with coilover springs, you can set a stepless lowering within the tested range, thanks to the threaded sleeves included in the scope of delivery.

The ST and KW coilover springs do not differ, only the KW coilover springs are offered for even more vehicles in the sports car and luxury car segment.

If you are only interested in a discreet lowering, our ST springs and ST coilover springs are the ideal product for you. With our ST sport suspensions you ensure a moderate lowering on your vehicle with a sporty driving behavior. If you are looking for even more driving dynamics in combination with a maximum lowering, our modern ST coilovers are the first choice for you.

Our springs are made of high-quality chrome-silicon material and are block-resistant even after installation. So they will not settle.

The most obvious difference is the possibility that you can choose a stepless lowering with a ST coilover suspension. This is not possible with a sports suspension. In addition, with our ST coilovers, depending on the version, the dampers can also be set either firmer or more comfortable.

Not all ST anti sway bars have the possibility of a two-way or three-way adjustability. Whether the stabilizer is adjustable depends on the vehicle.

The installation position differs, depending on the vehicle.

Every lift kit comes with installation instruction, and already at your selection in our shop you will see if the lift kit is for the rear axle or the front axle.

It depends on the respective axle geometry and vehicle weights, whether we manufacture the lift kits from a resistant polyamide composite material or from an aluminum alloy.
