Views: 1

After an extensive development and testing program we made this front adjustable camber arm available to everyone. The car was 3D laser scanned, the wishbone 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 adjustable caster arm.


  • Easy camber adjustability with turnbuckle jack screw.
  • Roll center adjustability with spacers
  • Increased strength and rigidity for improved handling performance
  • No rubber to bend, you will not lose the geometry set when doing alignment
  • You do not need to change the whole arm in case of wear of the ball joint. We use easily available replaceable high quality spherical bearings and uniballs
