I am just about ready to install my coil overs long story short - got the strutts and springs from a member on here - but the coil over sleeves them selves was way worn out due to excessive rubbing, so ordered from summit a new set and the welded 3 tangs onto the spring plate to avoid the spring moving of its centre thus preventing any rubbing on the coil over and a piece of rubber for the spring to rest on
a little close up of how it looks
here is the standard spring housing with 3 notches taken out to accomodate the 3 tangs. (yes you could just use m8 bolts through the holes - but my thinking is in wet weather it would give a little more protection to the upper area of the suspension housing)
here is the completed strutt (minus the original spring housing) - i put on a moog suspension bushing as recommended earlier on in this thread
will post pics once I have fitted and adjusted them

A couple of questions I have... First the springs you guys are using seem kinda soft. I have a Miata which is lighter and I run 530 lbs springs in the front and 350 in the rear. This car is my autocross car, but i want to start doing my Fiero next year. Secondly doesnt want one do a set up of these coil sleeves on the front? All i see is pictures of rear coilovers.

I have never seen the front with coil overs on - as most people either fit lowing springs or cut 1 or 2 coils of the stock spring which is acceptable due to the type of spring on the front - one thing to bear in mind with the front also is that the damper and the spring are located separately not like the rears where the spring fits on to the damper.

thanks Jon. thats what I was wondering about. I am looking to run mine for autocross purposes next year so I would want something a bit stiffer than a regular lowering spring. Have any suggestions?

without going off topic ref front suspension - now I am guessing here (as I am no expert ) what about koni adjustables as you adjust the stiffness of the ride and a set of front lowering springs ( i have suspension techniques) which i got from a member on here who I believe bought just the front set from jc witney then used QA1 12 300 springs in the rear over sachs or kyb strutts with coil overs on.

I just made myself some rear coilovers with my Konis. I got an AFCO coil over kit from Summit Racing for Monroe shocks/struts, 7 inch sleeves. I also got 350# 10 inch springs from summit racing.
I am posting to explain how I got my springs off because it was super easy and required no specialty tools.
1) With your whole car still assembled, blast the exposed threads on the top of the shock with PB blaster or whatever. Clean the threads up if they are corroded.
2) Grab the appropriately sized socket and allen wrench (this is if the impact gun will not get the top nut off)
3) Put the socket on the nut and grab it with vice grips. Insert allen wrench into the hex opening. Turning the vice grips, both of the nuts came right off.
4) Jack the car way up - This decompresses the springs.
5) If the threaded portion of the strut does not go through the hole in the bushing, I used a combination of kicking my wheels down and I took a punch, put it in the hole where the allen wrench goes and hammered until it popped through.
6) By now your spring is decompressed, and I unbolt the strut with an impact wrench from the rear knuckle and remove it, and after I take off the hardware still bolted to the car. When you reassemble there is no compressing of the spring necessary
This saves you having to get spring compressors which are a pain to use, and it is much quicker than using spring compressors. Sorry if everybody knew this already or someone posted it on another page of this thread, I did not feel like reading through all of it.

Does anyone have updated part numbers for the sleeves?
Thanks

The 2 1/2 in diameter was that outside or inside? The strut outside diameter itself is 2 in and 2 1/2 would fit pretty loose.

The 2-1/2" is for where the part (idk what its called XD) the springs sit on. That's why you need springs that also have 2-1/2" dia. Like the ones I posted. The ID of the sleeve is a bit over 2" and slip right on KYB struts and the metal ring the sleeves come with barely fits so that it won't move around the strut.
Check this thread out. will explain a lot better then I could and has lots of pics http://www.fiero.nl/forum/Forum2/HTML/118751.html
I used that as a guide when making mine. I used the same springs as him but not the sleeves as wanted to buy parts from same place so I just found some like it from summit to get everything from one place and that is what I found.
