Product Description

The SPL Parts SPL TRE NAPS tie rod end kit is engineered for Mazda Miata NA drivers who want precise steering control and reduced bumpsteer, especially during aggressive cornering or track use. By relocating the tie rod end pivot using adjustable spacers, this kit minimizes dynamic toe change as suspension compresses, resulting in smoother steering response, better traction, and reduced tire wear. It includes high-quality FK PTFE-lined rod ends for maximum articulation and CNC-machined aluminum turnbuckles for rigidity and adjustability.

Designed specifically for the 1989-1997 Mazda Miata (NA) with a power steering rack, the SPL TRE NAPS kit comes with both outer and inner tie rods plus stainless steel steering rack spacers to fine-tune bumpsteer. It's a premium, performance-oriented upgrade ideal for street or track applications where steering precision and handling feedback are priorities. Made in the USA with quality materials, this kit gives drivers greater control and confidence on back roads and race circuits alike.
