These are pretty self explanatory, and had these as spares should I ever break one. They are actually S14/S15 tie rods (M14 in size) as they are stronger, but will fit an S13 rack as the threads the rack end are identical. GKTech tie rods are longer than standard, so they are ideal for cars running extended lower arms, as they ensure full thread engagement in the Tein Rod Ends. Link below for full details. https://au.gktech.com/…/m14-super-adjustable-inner-tie-rod-1 As you can see in the pictures, these are brand new as if you bought them directly from GKTech. Price - £50 collected from Bristol (UK) or £55 posted. {} {}
