Frequently Asked Questions

Choose a category

The three ST Coilovers ST X, ST XA and ST XTA always allow the same seamless 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 made more sporty 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 unibal top mounts. When possible, depending on the vehicles design, the top mounts of the XTA can be adjusted in camber and/or caster.
The ST and KW Coilovers differ in quality and the housing materials and technologies used, there are no overlapping products. Most obvious is certainly the housings, which for KW are typically exclusively made of stainless steel or aluminum, while ST uses the common standard 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 GmbH facility in Fichtenberg, Germany.
Individual components such as replacement dampers, elastomer bump stops, dust shields, springs, top mount components or even complete struts can be ordered at any time.
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.

The coilover suspension and the technical component report, installation documentation, spanner wrench for adjusting the ride height, an ST rebound adjustment knob for adjusting the damping forces as well as the associated adjustment manual if the ST Coilover suspension features adjustable dampers.
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.
One wheel hub is not like the other. Various automobile manufacturers use different dimensions and bolt circle patterns for the wheels. For this reason, we have developed a variety of spacer and attachment systems for a fast and safe assembly to provide a widened track width for more than 90 percent of all registered vehicles.
The wheel spacer system you need, depends mainly on the spacer width that you want to install. For example, with our DZX wheel spacers (thru hole system with multi-hole circle) you can widen the track from 5 to 25 mm in precise 2.5mm steps per wheel. For 20 to 35 mm per wheel, our AZX bolt-on systems are the correct choice. Both systems are suitable for vehicles with wheel bolts or wheel studs.
Due to many different wheel & tire combinations that are possible for each vehicle, we generally recommend measure the maximum possible track width 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 or directly contact our Customer Care and Technical Support team 1-800-445-3767.
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.
Our ST shaft nuts are available in different versions and lengths, so that almost all DZX spacers can be used on cars with studs. Via our wheel spacer finder on the homepage, you can quickly and easily check, if our shaft nuts are also available for your car.
With traditional lowering springs your lowered height is decided before the purchase based on the springs specifications. But with ST Adjustable Lowering Springs, you have seamless ride height adjustment within the tested range, thanks to the threaded sleeves included in the kit.
The ST Adjustable Lowering Springs and KW Height Adjustable Springs only differ in that the KW height adjustable springs are offered for even more vehicles in the sports car and luxury car segment.
Within our tested adjustment range, the ST adjustable lowering springs provide a sporty, harmonious driving behavior with sufficient driving comfort.
If you are only interested in a discreet lowering, our ST lowering springs or ST adjustable lowering 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.
The most obvious difference is the possibility that you have the freedom to adjust the ride height on an 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 sportier or more comfortable.
ST sport dampers are also available separately, without the matching ST springs. But like when changing the brake pads or brake discs, also the dampers, suspensions and springs should always be replaced axle-wise.
Not all ST Anti-sway Bars have the possibility of a two-way or three-way adjustability. This adjustable depends on the vehicle.
With the adjustability of the anti-sway bars, you can directly take influence on adjusting the spring characteristic tighter.
