1. Before fitting wheel spacers, you need to make sure that you remove any dirt of rust deposits from the wheel hub.  It is important that this surface is free and clean from any debris.
2. Ensure that the wheel spacer can be fitted tight up against the wheel hub.  There must be no protrusions on the hub from nuts, bolts, clips etc.
3. You must make sure that when the wheel spacer is fitted that the wheel and tyre will not foul the suspension or the bodywork.  This is very important and should be checked before the vehicle moves or is driven.

5. When the wheel spacers are fitted, you must make sure that there is a minimum of 8 full turns on the wheel nuts or bolts when tightened.
