  • Steering ratios

    Has anyone on here played with the steering ratios on S14s? Since I am predominantly driving my car on autocross and HPDE, I was wondering if I could put in a quicker ratio on the steering.

    only option i know of it to locate and refurb a S13 Hicas rack and im not 100% sure that is a bolt in solution. but the Hicas rack does have a quicker steering ratio than the non-hicas S13

      HICAS rack is 100% identical externally to a non-HICAS rack. Bolts right in - it's tough to identify them if you can't measure lock to lock (need inner tie rods on to match up with FSM measurements).

        Or get spindles modified. Shortening the tie rod pickup on the spindle about 1/2" will net you 2.5 turns lock-to-lock or so.

          is there any way I can swap pinions for a quicker ratio?

            That'd require basically building a HICAS rack out of components which are not sold separately. So technically you can, but it's much easier to find a HICAS rack if you want a little quicker rack ratio.

            Changing the tie-rod pickup point makes sense.

            GKTech makes some nice billet aluminum front spindles that offer a modular tie rod pickup that can change your steering ratio and ackermann.

              or if you want to just try it and see they make steering quickeners for circle track that multiply the steering input, http://www.summitracing.com/search/p...ing-quickeners but even that would require some fairly decent fabrication
