Z32/S13/S14 - multi-link rear suspension swap


  • Thanks

  • What size Swaybars are you guys running? I've started welding mine together, and i need to buy a swaybar.

  • Would I be able to use any s14 ruca with the s13 suspension? Main reason because ive seen the spl and stance arms and they look like perfect half circles where as megan and battle version has more of a kink look. Would they all clear our coils?

  • The s14 arms are all longer, some by 5mm, some by more like 15mm…

  • What have you guys done to run the brake lines? My S13 subframe didn't come with the brake lines attached. Did you use the stock Z31 lines and attach it to the new subframe?

    This might have been covered somewhere in this thread but I couldn't find it.

    I made a point to grab the s13 line because I wanted to swap to it being shorter and less complex than the funky z31 setup.

    When I was installing the subframe, I just bent the z31 brake lines out of the way so that I wouldn't deal with them being disconnect and dripping.
    Come to find out that the brake lines used on the z31 are poly armour lines which are bendable without creasing the metal.

    So I ended up using them, bending them roughly to the location that I wanted. From there, I used a SS braided line to the caliper.
    Make sense?

    Yes it does make sense, thank you. In this case I could use my rubber lines to the Z32 calipers for the time being until I pick up the Goodridge SS set.

  • I forgot to mention that I removed the hard lines that clips onto the z31 LCAs along with the rubber line that that connects them.

    So to be clear for everyone else, you are using just hard lines that come out of the rear brake line splitter, then a rubber or SS line to the caliper, that's it.

    Exactly what I did. Pretty straight forward, s13 rear SS brake lines worked perfect from the z31 rear brake line splitter on each side.

  • Thanks Adam, you already answered my next question. Lol. So I should be able to use the S13 -> Z32 conversion lines for my Z32 rear calipers.

    Yes sir!

  • Can i use my stock 88t vented discs and calipers on s13 subframe with 5-bolt hub mod? Is there needed any modifications?

  • No because the s13 has a drum parking brake, you need to start with a z32 rotor, and while you could use z31 vented rear calipers, you'd probably be better off spending the extra for z32/r32 ones.

    Wrong.
