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.
Benefits
- Bumpsteer Correction
- Lightweight: 2.52 lbs (1.14 kg) per Side
- Precise Dynamic Geometry, Stability, and Handling
- Reduced Front Tire Toe Wear
- Maintenance-Free, US Made, PTFE-Lined FK Bearings
Materials
- 6061-T6 Aluminum Turnbuckle
- 4140 Chromoly Steel Tapered Stud
- 304 Stainless Steel 1/8" and 1/4" Spacers
- Anodized Titanium Hardware
- FK PTFE-lined Spherical Bearings (Self-cleaning, US Made)
Noise, Vibration, and Harshness (NVH)

The SPL tie rod ends are not a significant contributor to NVH. They improve the driving experience by reducing bumpsteer on uncorrected cars.
