WAS-425 Fitting Instructions

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.

Benefits:

Increased strength and rigidity for improved handling performance
No rubber to bend, you will not lose the geometry set when doing alignment

Features:

This is a bolt-in kit, no modifications necessary to the car
Inserts comes pre-assembled
Delivered with a tool which prevents bending of wishbone during insert replacement
CNC machined out of 6082 t6 aluminum
High-quality motorsport spherical bearings
