My drop spindle solution

My goal with this is :
1.5" drop
Increased neg camber
C7 hub bearing
Bolt on Brake bracket
Bolt-on steering arm to allow for adjustments to Ackerman, steering rate, Bump steer.
Fabricated from laser cut steel plate and welded.

Cad work is done, Some steel parts cut and welded. I should have this thing on the car for fit testing in a day or 2.

Re: My drop spindle solution

Test fit on car. 3D printed steering arm not stiff enough at all for bumpsteer testing, Will have to rig something in metal. Looks like this idea might work, With the camber plate all the way outboard the camber sits at ~ Neg .5 . Going to ponder if thats where I want to leave the design.
