recommendations from SPL
240SX with stock knuckles: Use with OEM 300ZX (Z32) inner tie rods or Tein 350Z (Z33) inner tie rods only.
240SX with modified (increased steering angle) knuckles: Use with S14 inner tie rods (OEM, Tein, Ikeya Formula, etc.)
personally i'm running the new PBM s14 inners with moog oem outers. (i'm running roll center corrected knuckles so i don't need the "dropped" style outer tie rod ends)
