I'm converting the front struts to adjustable coilovers, but I can't find a good/safe way to make the rear springs adjustable. Anyone have any good ideas? Pics would be helpful :) or a place to buy a setup. And yes, I have searched around =P.

Do these use a multi-link with coil springs or a leaf spring?

Multi-link/4 bar rear suspension. Basically, you are going to have to find an adjustable spring perch and weld it onto the rear end. I believe that somebody(megan?) makes one for the AE86 that will work with our cars. Of course, you are going to have to either short shock the rear(look for camaro rear shocks) or figure out some sort of restraining device to keep the spring captive. Somewhere, I don't know if it is here or 1stgencelica.com, but there is a thread where some one did this to the rear of their celica. If I can dig it out of my feeble mind I will link it here for you.

Yeah, can't use the megan rear adjustable coil overs without major structural work on the body. Shock towers in the celica were never meant to take the full weight of the car. You can do it, but the weld-in spring perches are much easier.

Yeah I figured, so the only way to keep the springs from possibly coming off of the perch is to make sure the shock won't extend far enough to let it happen?

Yes, ideally you'd want shocks short enough to prevent it, or some type of droop limiter. 8)

Camaro shocks are good enough for a 2 coil chop in the rear of the celica. I know, plus, DatsunFreak can attest to how low my celica sits... I had to cut the bumpstops in half just to get some suspension travel.

Don't know if they are shorter than the mustang shocks. I took two coils out of the rear of my celica(76 LB GT) It was riding on the bumpstops for quite some time, till I realized it. I cut the bumpstops in half and they are still too tall. I have to jack the rear up and compress the springs before I can bolt in the shocks. Only way to know if they are shorter is to look at the specs on both shocks. Mine were only 35$ or so from autozone, that is why I went that route. Most likely, it will all change when I get the 16" conquest rims on mine, but camaro shocks are the standard swap in the rear.

i just bought some for an 89'. they are the same length/stroke as the mustang shocks. the only difference is that the buttom eyelet has a bushing with a metal sleeve, whereas the mustang shocks just have the rubber bushing.

Anything from about 82-2000. They are pretty much the same shock. I have used both 3rd and 4th gen shocks on the celicas.

Sort of on topic, but I used zipties to keep the front springs in my old R30 captive before I went to coilovers ;)
