Most Heim joints have limited angular movement. (as opposed to =
rotational movement)Unless your suspension has very tightly controlled =
travel, you'll have to find special, high-angular joints (they are =
available). =20
Or set up the system to take advantage of the rotational capabilities of =
the joint.
Then, too, you'd want to devise a method of protecting those joints from =
moisture, debris, etc. Only very light-duty spherical rod ends (aka =
Heim joints) come with rubber 'dust' covers'. The heavy duty units =
don't.
Next, you'll want to drill and REAM the bolt holes and find precision =
bolts that fit those holes and the hole in the rod end with minimal =
clearance. Otherwise you'll have potential for excessive play. (just =
torquing the nuts down is not adequate) This is why all OEMs use the =
tapered hole/stud...cheap way to get zero play at the fastener.
Many race cars use this Heim joint method, but they have frequent =
replacement schedules for these components. It isn't really =
satisfactory for most street cars.
Is bump-steer all that much of a genuine problem for us lowered-car =
owners? Or is it a perception?

Drill the whole for the tierod and then use a hiem joint with a grade =
8 bolt. simple solution to the problem.=20

umm, how about just machining the hole and installing the arm =
inverted (with
no spacer). that will get you most of the distance you are looking =
for. all
you will have to do is worry about the inverted tapered hole, which =
i would
think a machine shop could replicate. the hub carrier metal exists =
to make
the bottom half of the taper. a simple weld could fill the top area =
before
the taper is made.
