Bump steer

[3W Hank]

If one use a 32 arm on a steeringbox in a 32 frame and use hairpins, I note the angle is way lower than meet up on hair pin bolt.
I guess many cars is set up like that, just wonder how it work out.
Here is a example and maybe my set up will be.

On most of these kind of setups everything is wrong including the Ackermann centers etc. Just my opinion

IF angle persists between drag link and radius rod, there will be BUMP STEER. The greater the angle, the worst the bump steer will be ..... simple geometry. Try for initial parallelism between the two suspension members for best bump steer situation.
