The SPL NA / NB Miata Tie Rod Kit allows for bumpsteer adjustment by allowing the tie rod end pivot to be relocated with the use of spacers on Miatas with the factory manual steering rack. This results in less dynamic toe change (aka bumpsteer) as the suspension compresses (bump) during cornering and over rough roads, resulting in more predictable handling, less tire shoulder wear, and better stability over rough roads and track curbing.
