Has anyone or does anyone think it is possible to keep the original setup (I have WCF springs front and back) and install a threaded sleeve over the bumpstop up front with a threaded spring perch so the front is adjustable? I do not want to put a shock in there (I'd like to leave the shock and A-Arms stock).
My problem is that the springs right now are too low even after giant washer spacers and I'm tired of always dismantling the front to add or remove washers. I just want it adjustable since it seems to slightly change height on its own every once in awhile.
I have a setup similar to that on both ends of my Saab 900, which uses a discrete shock/spring at all four corners. Works great! You just need to be sure the adjustable perch matches the ID of the spring.
That is close but I was looking for something more like the rear coilovers where something can completely go through the middle and it is adjustable (not tack welded in). My main problem is finding something that fits perfectly in where the factory spring goes into right now. There seems to only be about a half inch space.
If you run aftermarket lower control arms (on an 88), you can run coilovers on the front. Stock control arms are not stout enough to carry the weight at the shock mount. You are out of luck on pre-88's, crossmember and control arm replacement is your only option.
I fabricated an adjustable spring setup on 3 86 Fieros to date. All are autocrossed and track regularly. The lower control arm is reinforced and a threaded sleeve with spring installed. the shock is in the stock location but uses an adjustable QA-! unit with custom mounts. Works great so far. Over 4+ years on 2 of the cars. The third was totaled and was replaced with an 88 GT. I have built a true coil over set up using the QA-! Single Adjustable threaded shocks for that car and 2 other 88's as well. One being mine. Same AX and track schedule. Been over 6 years and works great too.
So you put the sleeve and perch upside down on the bottom portion of the spring and reinforced it?
Is it possible to see some pictures if you have some? Thanks
EDIT: Wait what am I thinking that is the normal way, I was originally thinking of installing them upside down on top of the spring... not sure how that slipped my mind haha, would still be nice to see pictures if possible, thanks!

I will see if I still have the lower arms that were salvaged from the old car. I think I saved them. As well as the sleeves. The top of the springs fit into the upper stock spring perch location. I used a 3" Fernco cap on top of the spring to cushion and locate the spring in the perch. Pics may take a few days. having a wisdom tooth pulled today.
Thanks a lot for those links, that is exactly what I am looking for. It seems this may be more work intensive than I planned... I think if I go through with this I will have to remove the bump stops completely.

There is also another alternative to give you adjustable front height. I ended up using air shocks on the front and installing a small compressor to get my car out of the driveway without dragging. This was done on an 87 Mera but could be installed on other Fieros as well. Pictures can be taken if needed and I have a good e-mail address.
Inspired by Mcguiver3's setup above, I've been researching this a little more, and I think I've come up with a combination of components that would make this possible with only having to modify the lower control arm. That way you could switch back a set of stock lower arms if you ever wanted to, and run a stock setup again. My idea is this: Start with a set of these http://www.jegs.com/i/Ridet...entProductId=1391960 Disassemble them, and just use the body/lower eye mount. You won't need the shaft, or top mount. Then weld these to the lower control arm (after removing the stock spring pocket and reinforcing with a flat plate) http://www.jegs.com/i/AFCO/921/20137/10002/-1 Then use these springs. http://www.jegs.com/i/QA1/122/10GSF350/10002/-1 Using tapered springs would avoid needing to modify the top spring mount on the fiero crossmember. I'm not sure on the spring length, I haven't done any calculations, but you get the idea. Your thoughts?
You can use two Allstar 56118 adjusters ($40 each) welded to the lower control arm. They will require a shorter spring, but then you have a simple means of adjusting them. You might want to notch the outer ring for a spanner wrench or drill the threaded tube right at the spring support so you can use a screw driver to turn them for adjustment.
However you do this, you likely need to trim down the factory bump stop sleeve to make room.
