Jetpilot or anyone that has Coilovers

[inline350]

When you put on the coiovers what happens in the rear where the oem spring used to go??

[rchboy]

a lot of kits come with a spring to put there.

Coilovers are a strut spring combo.... it sounds like you got struts.

[folgrz]

it comes with a new spring and perch so you can adjust to the level of ride height

on the 350's the strut is seperate from the spring in the rear

[inline350]

nah the ones that i got get rid of the original placement of the perch and its a full coilover

look at my other thread to see pics

Hey man, I don't run coils, but the factory strut had to bolt somewhere. Shouldn't the coilvers just bolt in there and the factory spring perch is left open

To be clear, any spring and shock/strut arrangement where the coil spring is located on the shock/strut itself is technically a coilover whether it allows for height adjustment or not. The term has become used incorrectly and has become widely accepted as such. Not that I'm trying to a stickler for this, but given the Z's rear suspension set-up where there is not an actual coilover of anykind.

The Z doesn't use struts either. Struts are locating members of the suspension, where as shocks are not. Basically, if you removed a strut from a car equipped with it, the spindle will simply hang by the lower control arm. With a shock, you can remove the shock and the suspension will still travel according to the intended geometry.

I haven't really paid much attention to what is out there now, but what I have seen is just essentially the threaded collar portion used with an adjustable perch with a spring on top in place of the original spring. They keep the shock separate.

Such a setup you describe might be dangerous (coil-over shock in the rear). The shock's mounting points will likely have been tested and perhaps built to handle the loads seen by a shock. As a shock in such an arrangement is not going to see nearly the load a spring will, it may not be able to handle it. Even if it could hold the weight, however, its possible the chassis may flex more than it should.
