  • S15 subframe

    I just bought an S15 subframe. And an S14 (the whole thing). And I still have my S13 subframe. Measurements and pics to follow. I threw away my diy bumpsteer gauge though.

    Sweet! Looking forward to seeing the results.
    I hope the S14 subframe has the same geometry as the S15...the S14 one is much easier to get.

      sorta unrelated..... I also have a Z32 subframe at the house if anyone needs any measurements off it.
      all of the arms are the same length as on the S14, but the mounting points and overall track width is wider since the fixed center portion of the subframe is 2-3" wider.

        You son of a gun, i hope its not from the guy I planned to get it from. This is the surprise I mentioned in my thread lol... hopefuly its not the same guy cause he told me he'd get me a quote and pictures on Friday....

        For arm compatbility I had a list of stuf I got from Kuah. Basically you need S14 LCAs, S13 RUCAs and I believe S14 traction arms. For fitting into s13 you may want the touge factory offset solid bushings.. and I believe you'll need solid differential bushings (not sure on this one myself --- the irony I have an s15 hlsd and axles but s13 housing).

          Are the S14 traction arms longer than the S13 ones?

            Out of curiosity, I've read S15 rear LCA's are aluminum. Is there any truth to that statement? If, it is true, are those rear LCA's easily swapped between different generation sub frames?

            Sorry for going completely off course with your thread.

                I want to stop by sometime to check out where/how exactly they reinforced it, to get an idea on what to do to my spare.

                  The lower arms are not aluminum. My particular setup has Nismo arms (reinforced, steel, silver paint). The shop also had another S15 there, which also had S14-looking steel RLCA's.

                  Longfellow, I won't be around this weekend, but you can stop by tonight or next week sometime. There's not a lot of obvious stuff going on. Maybe I'll fill it with 16pcf foam...

                    I was planning on running solid diff mounts and then Foaming the subframe.

                      Does foaming the subframe help with noise, or is that for rigidity?

                      Maaaaan my car is loud after I stripped the interior! I'm running ES bushings on the diff, and aluminum subframe collars. the diff is loud as a chainsaw now, even only at low speeds.

                        It helps with both.

                          cool.. I'll look into it. I'm not too worried about the structural portion since I'm running no more than 200whp... A couple strategic braces and gussets will significantly help there if I ever need any bracing.

                          I wonder if just the cheap handi-foam crap will help with the noise though???

                            You need structural foam, not Home Depot crap.

                              Well Handi-Foam is the right brand you just need the correct weight/density.

                              And I would say Foaming it will gain more rigidity and more sound damping than anything else.

                              It would definatly shut up alot of drivetrain noise.
