Standard cars come with a rubber/metal combination bush, which isolates noise well and is usually the only option for a manufacturer.
However, when it comes to freedom of rotation and accurate location of the wishbone ends under load, it leaves a lot to be desired.
The Nitron wishbone bearing kit replaces all the inner rubber bushes with 15mm Teflon-lined spherical bearings. On either side of the bearing is a spacer machined from 7075-T6 hard anodised aluminium. These spacers have an ‘O’ ring seal placed on them before they are inserted into the bearing. There is no need to tighten these into a particular position like rubber bushes and, as they are fully sealed, they will not require any maintenance.
The kit comprises of 14 shorter and 2 longer bearing assemblies for the front end of the rear lower wishbones.
