Took out the existing steering rack mount and built a new one. Old one was from the Saturn Sports Cars/Book guide, which was meant for a escort rack and had the opposite mount to pinion angle. Meaning our Miata rack had a large angle kink between the pinion and steering shaft. The existing mount was quite flimsy, and we saw 1/4-1/2” of movement when turning the wheels at standstill. New rack is made with 1x2x1/16” thick rectangular tubing welded to the chassis and then 1/16” straps to further increase stiffness. New mounts are much stiffer and reduce the angle between the pinion and steering shaft.
