One of the most cost effective mods on the market and easy to fit. Simply unbolt your wheel, give the bore of the wheel and the face of the hub a good scrub with a wire brush to clean off any dirt, rust or debris, apply a little copper grease or similar to stop the faces sticking together and slide the spacer on to your existing hub. Check the spacer or adapter is sitting flush against the original hub with no visible gap, gently position the wheel on to the spacer spigot taking care not to damage the machined surfaces, secure the wheel with the extended bolts and torque them to the required spec.
