Since the Ford uprights are really heavy (16 kilos each) I decided to design a pair of aluminum ones . To make things easier I'm sticking to the original dimensions .

This shows the bottom plate which is removable to make ackermann easier to change .
I made good use of the lower spherical bearing bolt . Its an m14 bolt threaded in about 20 25 mm of thread in the upright .
Additionally two m12 bolts hold the plate in place .
The top joint uses the caliper bolt (another m14 bolt) and an additional m12 bolt . Lower bolt on the caliper will thread in the upright itself .
Thickness there is 20mm . The same as the thickness of the caliper mounts .

Possibly overkill, but that's what's on the caliper .
The ones I have here are from the rear of a porsche cayenne 4 piston and fairly light . Almost 800 grams less than the original ford ones .
This design uses the original 260 mm discs and aluminum hats .
It's a bit of a tight fit, which is the reason for the windows in the hat itself .
That I plan to hold with 10 M6 bolts .

I should point out that I plan to use 7075 . I'm a bit concerned with the threads on this .
Haven't worked much on aluminum . (not even a mechanical engineer to be honest )
TL:DR Critique my design .
P.S. The first drive will be with the original uprights . This bit is just an improvement and not a necessity and I want to go for a drive this summer .
