S14/R33 ones are 290mm
the issue here is the rods on the rack not the caster, people even run 10degress of caster ( say 6 more then "center" ...)
rack ends might be from another car or lock spacer, so too long and of course i'd assume that the rod ends are adjusted all the way, make sure the rubber boot isn't hiding some more thread on it
i think cefiro rack ends are m14 and are the same length as the s13 with is shorter so if all else fails give that a go
