Newbie question about spring perch adjustment

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

 

Lowering Ferrari 512TR, 348, F355, 550, Mondial T?

Realize that the balance and handling characteristics at the limit change when you adjust ride height and/or rake.

Some good info in my project thread, fwiw

 

Thanks. Great information.

Yes indeed:

 

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.
