After an extensive development and testing program we made those rear spring wishbone bushings available to everyone. The car was 3D laser scanned, the bushing was CAD developed, we have tested the CAD model with FEA (Finite element method) and performed road going tests so you can now buy our rear spring wishbone bushings.

One of the bearings in rear knuckle (upright) comes as uniball from the factory (mount number 18 on the picture). This kit enables to change the second one from rubber to uniball (number 13 on the picture).
