Remove one of the half bushes, add another grey connector like the one holding the balljoints in and extend the axle to 5 studs. Then put a ball joint in that connector and you're good to go.

Some time has passed and I am currently working on the first version of this car (I'll revise it later to eliminate things such as chassis bending and excess weight). I took your advice the day you posted it and wow, it worked perfectly! Saved me a lot of time, and since then I completed the frame and started on the rear axle. I tried multiple setups which all had some underlying issues, but I think I came across a practical solution.

I had to raise the ball joint on the rack a half stud higher for the perfect angle, and as a final result the bump steer is practically zero.

I'm using efferman's 3D printed u-joints, hopefully they'll hold up.

I'm showing the possibilities and challenges in building a 'performance' car with this build, as well as gaining more experience for myself. I really hope this build will work out in the end, wish me luck!
