    DTM style trailing arm project.

    Developing DTM style trailing arms using stock e30 knuckles.
    This prototype will have to run true coilovers.
    Im thinking about making inboard spring options... depends on interest.

    Have to get them powdercoated and figure out a rear coilover to test them.

      subbed. In for updates.

      Did you use one of the kits for the heim adjuster or make your own?

        IRP kit.
        we looked into getting our own machined.... pricey

          yea that's what I figured, cool stuff!

          True coilover would rob a bit of inner tire clearance though correct? I'd like to see an articulated spring perch mounted a bit lower than original to give more spring travel.

            depending on the coilover, gonna try and run sleeves on my skinny bilsteins.
            Interesting thought with the spring perch.

              something like these. There're a few companies making them. Spring/ride height is adjusted from below by turning the threaded shaft. I've been trying to visualize how to make them work in my stock arms.

                interesting. it would be hard to mount a perch lower than factory... but not impossible. plus to work with ^ those id imagine the perch would have to be very specific to just that

                    Great work !!!
                    Now raise the subframe with welded mounts. Just like BMW Motorsport used to do.

                      Really cool job.

                      Just throwing these out there if you want to make a heim...

                      Repairable Heim's are the way to go now, lots of different sizes etc.

                            made a beefy rear strut brace for my car to test these.
                            i bolted the plates above and below the strut mount, ideally I would weld them in but I daily this particular test mule.
                            It's nothing fancy, just some thick DOM.

                              I like the dual sheer mount for sway bar link.

                              just cut to the chase, no bracket..

                              I was up above it, Now I'm down in it ~ Entropy - A Build thread.
