General Lower wishbones being made up

[Abarth 695]

Hi,

I am using a local firm to build me some front lower wishbones which will be fully adjustable. You can find similar kits in Europe but I prefer to have someone locally build it knowing that it works and id fully adjustable. This kit gets rid of the leaf spring and uses coil overs instead.

I have also seen people modify the upper arm. Does anyone know why?
