i JUST BOUGHT THESE, (JUST TO SEE IF THEY COULD BE USED ON A FIERO). for $39. you get 4 Sleeves w/ locks, 4 springs (6.5") and assorted o rings. the sleeves work every bit as well as summits. the springs seem to be a "rate" that I can live with. you remove most of the original lower spring shelf, BUT LEAVE the weld there. they have the same "shortcoming" as Any of the parts available , having to make an upper sleeve to go down into the top of the spring to keep it in place (when you jack up the car). ** but for a Total price of $39 you can make 2 Sets of Coil Overs ! ** Just thought I'd pass that along
I suppose there isn't a way to know what the spring lbs are...
There are online formulae to work out the spring rate from the wire thickness and number of coils. Had a couple of these Honda kits, one was 325lbs, the other 350.
Since you have added these to your car, does the shorten spring effect wheel travel? Correct me if I'm wrong, but that seems like the shortest spring I've read of being able to used on a Fiero coilover.

I'm running the Eibach coilovers which are 7" and the sleeves are so short that I had to add a steel sleeve on the bottom to add some height. You can see it in black. Also, even though EVERYONE does it, I don't like grinding off the perch down to the weld. I simply cut off the front portion since that is the area that would hit the wheel/tire. I really don't like the thought of creating excess heat from grinding.

I thought they ground the perch off because the sleeve usually goes down completely over it, does yours not because the spring is so short?

If you want to use a 12" spring and lower the car much, then you need the sleeve to sit below the weld bead. For extreme tire fitment, some like to use a 10" spring and keep the sleeve above the weld bead, this allows the wheel/tire to be as close to the body of the strut w/o needing any room for the thickness of the sleeve or the adjusting collar.
When using 10" or shorter springs and depending on spring rate (lower spring rates are worse), you can reach coil bind before your end of suspension travel, so it helps (but costs more) to start with springs with advertised specs.
The use of the eBay coilovers have been around and discussed many times over the years. The primary issue is even when they are for the exact same application, some of the sleeves in the kits will be less than 2" ID, which means they won't simply slide over. Some will, some won't, sometimes 2 in the box of 4 will and the other 2 won't... results are very hit and miss.
FWIW, I build all my coilovers to customer spec, every component is new with stainless steel for all studs, washers, and nuts, and if the weld bead is removed, it is turned off with a lathe, so there isn't any excessive build up of heat. Definitely not the cheapest route... but they look great, are built to your spec, and are plug & play.

Must say that the installation of coil overs looks nice and most likely improves the handling and frees up space for wider tires. I have heard the downside they make the ride harder.

Ah, China standards.

Doesn't have to. Some people think you need real stiff springs or you'll get body roll, so they go too firm. IMO Ride depends on your spring rate vs car weight, also depends on size wheel and which exact tire is run. And rebound control if you have adjustables.
My smallblock car has 400lb springs in the rear coilovers and is lowered I'd say a little over 1.5 inches, 17 inch Kumhos.. It rides pretty nice though, the engine weight requires the higher lb springs. The stock powertrain Formula with stock suspension and when it had 17 inch Michelins rode harsher. (Same tire inflation on both.)
