    The back of my car (355) seems to sit low. Not much but it looks too low to me.

    To adjust the back end up.... do I move the spring perch down? Or up?

    What is a full turn worth in ride height?

    Sorry for the newbie question but adjusting the perch on my other cars always involved a grinder & a welder :)

    Ive notice the back of the 355 droops at it ages. The new nose high stance looks horrible (unless you a baja 1000 truck) and i imagine its very bad for high speed stability.

    You can lower the nose like i did, or raise the back.

    To raise the back you need to raise the perch by turning it counter clock wise.
    I suggest renting a sprint compressor from autozone to at least remove some tension on the perch to make it easier to turn. Mark the perch with a dot of paint and start with 3 or 4 turns, set the car back on the ground and roll it to let it settle and repeat if necessary.
