SPL Parts Adjustable Tie Rod End Kit w/ Bumpsteer Correction for 1989-1997 Mazda Miata - SPL TRE NAPS

The SPL Parts Adjustable Tie Rod End Kit (Part #SPL TRE NAPS) is designed to correct bumpsteer on the NA Miata by relocating the tie rod end pivot using precision spacers. This reduces dynamic toe change as the suspension compresses, resulting in more predictable handling, improved stability over bumps and curbing, and reduced front tire shoulder wear.

This complete kit also includes new inner tie rods and stainless steel steering rack spacers to increase steering angle for drift applications, making it an ideal solution for street performance, track days, and drifting.
