For the past few months I've seen Honda Coil-over kits seperated and sold as Fiero coil over kits on ebay for $150. Every time I see it I cant believe people bid on it. You can order all the parts and make your own coil over setup for around $100 and it will be done right. This post is basically what I did to my 88. It will work the same on all model years. This is for the rear only. In the front I have lowering springs. Other options for the front are rodney's lowering balljoints, Helds front coil overs or drop spindles.

When I wanted to replace my rear factory cut springs on my 88 coupe I decided I wanted coil-overs. I rembered reading about being able to use Honda coil-overs and not having to cut the perch off of my struts. Sounded good to me. I have plenty of friends who are into Honda's. One of them had an old set of coil-overs from his car that he gave me. It was a kit like this: http://cgi.ebay.com/ebaymotors/98-02-HONDA-ACCORD-JAPAN-JDM-COILOVERS-COIL-OVER-OVERS_W0QQcmdZViewItemQQcategoryZ33586QQitemZ8007620660QQrdZ1

I removed my cut factory springs and installed those in their place. The Honda coil-over comes with a tiny 8" spring. I'm not sure what the spring rate is, but it rode like crap. Was really harsh an made a lot of noise. After a few months of driving around with this setup I decided it wasnt working good at all. I needed to remove the spring perch from my struts and get a longer coil over spring. I did a search at www.summitracing.com for coil over springs and came across the QA1 coil-over springs. They come in all kinds of lengths and spring rates. I ordered 3 different sets because I wasnt sure on stiffness and spring heigth. I ordered two pair of 12" springs. One pair was 325lb springs and the other was 350lb springs. The third pair of springs were 10" springs and 350lb. The coil-over springs have a 2.5" ID. Links here: http://store.summitracing.com/default.asp?target=partdetail.asp&autofilter=1&Ntt=QA1+spring&N=0&part=HAL%2D10%2D350&autoview=sku&Ntk=KeywordSearch
http://store.summitracing.com/default.asp?target=partdetail.asp&autofilter=1&Ntt=QA1+spring&N=0&part=HAL%2D12%2D350&autoview=sku&Ntk=KeywordSearch
The 12" springs did not lower the car enough for me. They are good for about 2.5"-3" lower than stock. My car is about 3"-4" lower than stock so I needed the 10" spring.

I removed my struts so I could cut the spring perches for the factory springs off. You have to be careful not to get the struts too hot when removing the spring perches because you can ruin the strut! Once the perch was completely removed I painted over the are where I had cut so it wouldnt rust. Once the paint dry's install the Honda coil over sleve and adjustible perch onto the strut and slide it all the way down to the bottom. Next install your new coil over springs then reinstall your struts on your car. Then reinstall your wheel's and lower the car down. Measure your ride heigth and adjust to where you want it. Keep in mind the springs will settle/sag a small ammount.

After setting my ride height I took the car out for a drive. My ride is 100% better and it's a lot quieter that it was before. It rides really good now. I have about $100 into the rear coil overs now but it's still cheaper than Helds setup and it's the exact same thing. I'll get some pictures of my installed struts and post them up. Keep in mind my car is really low. I have about 1/2"-1/4" wheel gap. The car sits about 2.75" from the ground.

Do your wheels and tires have room to tuck inside the wheel wells or is your suspension so tight that you only need that small gap for movement? It looks really good either way.

The wheels have room to tuck. I dont know if they do. The suspension is stiff but it still rides good.

Just like my setup! I'll be doing the same thing on my 86GT. I think I'll install drop spindles on the front of the 86 too instead of cutting the springs like my 88.

I used the WCF front springs that they sell with their coilover kit. The ride height is perfect. about 1.5"-2" lower than stock. I got the 350# springs and wish I would have gone to 400#. I would go to 450# but I don't know if they have them that stiff. The 350# are okay for a street car, but for a dedicated autocross car, there a bit soft for my taste. They would still rattle your fillings over bumpy raods. When I setup the suspension on my 88 GT I'll look for other options in the front. Overall, I'm happy with the WCF front springs.

I know what you mean about the 350# springs being a little soft for autox but I couldnt imagine anything stiffer on our road around here! Michigan roads suck!
