Ikeya Formula Reinforced Tie Rods (S13 / S14 / S15)

With wider, grippier tires and modified knuckles adding big steering angle, factory tie rods can lack stiffness at high G. Ikeya Formula splits the inner socket (ball joint) and rod body, so thread engagement stays safe even with extended lower arms, and the whole tie rod is stiffer for long-lasting durability on track.

Sold as a left/right set.
