The wheel spacers are attached to the original vehicle mount using longer wheel bolts. The assembly is very easy. Simply put the wheel down, put the track widening on it and then mount the rim on the wheel hub using longer wheel bolts. The wheel spacers are produced on the most modern CNC-controlled saws, turning and milling centers. Please order longer wheel bolts at the same time! FK offers 4 different types of wheel spacers
System A without centering , this track widening is a kind of disk on which the hole pattern of your vehicle is integrated. The hub diameter is also taken into account. With this type of vehicle, it is important that the series hub has a longer centering than the track widening so that the rim is also centered over the series scar. If the serial scar does not center the rim, the rim must be centered using the wheel bolts / wheel bolts. This means that the screws in the unloaded vehicle are tightened to the nominal torque! Fixing screws not included in delivery.
System A with centering , this track widening has a centering over which the rims are then centered. Therefore a rotation is also granted at high speeds. Before you install or order a wheel spacer without centering, always prefer a wheel spacer with centering if technically possible. However, note the standard height of the hub. Fixing screws not included in delivery.
System B with centering , in this system the wheel spacer is attached directly to the wheel hub with the short head screws supplied. Then the rim is attached to the wheel spacer using the original rim bolts. It is important that you are fastened a maximum of 5-7 screw turns in the wheel spacer! This has to be checked before mounting to the rims with the wheel spacers.
System B + with centering , in this system the wheel spacer is attached directly to the wheel hub with the short head screws supplied. Then the rim is attached to the wheel spacer using the original rim bolts. The screw fastening is guaranteed 100% by pressed steel beeches! It is important that you are fastened a maximum of 5-7 screw turns in the wheel spacer! This has to be checked before mounting to the rims with the wheel spacers.
