    Lowering Rear

    Wanting to lower the rear of my car more. However the trailing arm can only go so far up when lowering. The point where the shock bolts to is off about an inch when i try to lower and does not move. Do i have to remove axels to lower further? Thank you.

    Picture is just for referance. When i lower more the shock no longer can align at the mounting point.

      me thinks you should not be toying with the suspension if you can't figure out how to get the shock to mount to the trailing arm.

      from what i'm gathering from your post the trailing arm needs to go up more to mate up to the shock, correct? throw a jack under the trailing arm.

      or if you are saying the shock is bottomed out and is too long than you have the wrong shocks.

        release your E-brake. that's what is holding the suspension up.

          I've jacked the trailing arm as high as possible and it still won't reach the shock. I am running a coilover setup so the shock spins to shorter lengths when i lower it. Preload is set at 0 with adjuster and lock ring on the spring.

            So you have a damper body that threads into a carrier for the lower eyelet right?

            Sounds to me like you have the shock body threaded too far into the carrier.

            Are these e30 specific coilovers?

              Have you taken the spring out?

                    Here is a better picture for clarification of the issue. With spring in fully jacked trailing arm is about half inch or so short of the shock mounting point. From what i understand i am supposed to lower the car further by spinning the shock body? The spring is meant for preload setting only and not for ride height adjustment? I have tried taking the spring out to mount the shock which works,but i am unable to fit the spring back in due to how short the shock is spun. These are e30 specific Broadway Static coilovers.

                          Yup.

                          Exactly why I asked about the damper carrier.

                          That entire arrangement makes no sense.

                            From what i understand it is the spring that is preventing the shock from reaching it's mounting point. The shocks are adjustable as well as the spring.

                              you should be able to extend the shock to reach nearly full droop. even if the springs were in there, it doesn't matter - it's too short. on a coilover spring the shock shouldn't be holding the spring compressed, and that's a really short spring anyway.

                              even if you managed to get it on there, what will happen is if you hit a bump or go around a corner, an unloaded wheel will lift off the ground providing no traction because it will be unable to extend past the length of the shock. not good..

                              if the cheap Chinese shocks you have can be extended any further, then that could make it work, but it won't droop very far without that short spring falling out.
