CNC made aluminum Uniball rear suspension system

Very, very nice!
What part is the 'bracket'? Anything connected to the trailing arm should be as light as possible as its unsprung weigth. Alu would be preferable over steel with that thinking.

Bracket is the part that used to attach whole system to the arm Uniball bearing housing is aluminum.

Yes, i would too prefer aluminum, definetly the 7075 T6 series aluminum, but steel bracket is in this pricerange.

Strengths: Normal steel is 355N / mm2, 6082 T6 aluminum is 270N / mm2, 7075 T6 aluminum is about 500N / mm2

All test done again with 2000kg.

These look amazing. Will they work with the early steel arms?

I'm very interested in getting a set of these, how soon are you going to start making these and what kind of fulfillment time do you expect before getting them shipped?
