Wheel hub is not like wheel hub. Numerous automobile manufacturers use different dimensions and bolt circle patterns for the wheel mounting. For this reason, ST Suspension 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.
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.
Thanks to the conical shape and the high-strength composite material of ST Suspension 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 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.
The ST shaft nuts are available in different versions and lengths, so that almost all DZX spacers can be used on cars with studs.
