New spherical ball joints made of a really hard aluminum. They provide a great weight saving at the extremes of the car and improve the softness of the joint with the plastic ball joint.
They fit well in all the large scale car brands in combination with the screws of small head 300010, 300011 y 300012.

These screws with a reduced head especially made by us are inserted inside the ball joints that fix the uprights, a solid solution, light and neat. There are three different lengths to choose, 14mm, 16mm and 20mm.
