I know URAS sells something similar but my new idea is to move the bracket up so the rack can come farther forward than the exsisting design.
This should eliminate overcentering and bumpsteer as well as steering feel and response.
The NEW design eccentric bushing set shown on the left, standard bushing in the center, and new rack position shown on right (without e-bushing for clarity). Even though these are shown flat, they sit in there at an angle. CAD is for S14 version.
