Fits S14/S15/Z33/some S13. This CNC steel offset spacer adjusts the pivot point of the inner tie rod forward 36mm and features a black zinc coating. It is for cars with high caster setting and high steering angle that causes severe over centering making the steering wheel hard to turn as the tie rod looses leverage at full lock. This offset spacer does cause some stress on the steering rack itself, so for all but the most extreme caster setting the eccentric steering rack bushing or Rack Relocation is the preferred method of reducing overcentering. Sold by the pair. Early S13 rack can use this product if cut new notches in the end of the rack to aim these forward. *If used with eccentric rack bushings (4-5mm forward) you must grind the FLCA mounting nut/bolt in half.
