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
• Includes all necessary parts to mount on the car
• Can be used with OEM wishbone and subframe

If you use lockout plates to block wishbone movement on the subframe, it is necessary to correct the camber setting within the adjustable upper bent link. You can find it here LINK.
