Very nice write up and presentation. Great information and informative how-to.
This process is going to be the same for a set of KYB's on pre-88 as it is on an 88, yes?
What's the basic difference (if any, other than tube diameter) between KYB's, KONI's and the stock strut?
Am looking into doing this mod on an 88 chassis that already has KYB's installed, so that's what I'd want info on.
TIA to anyone who may be able to shed light on the subject.
Again, great how to write up! Thanks for taking the time and effort and sharing.
HAGO!

Well thanks to CarDomain doing and update that scrambled everyones pages.... I can't push the greasable fitting write up through like I intended. I had it 99% done and they updated things and now the pictures are pulled out and the words are misordered and all broken into multiple posts. What a mess. Hoping a fix is coming soon so I can get back on it![This message has been edited by redraif (edited 09-15-2014).]

Will this work the same on an 86? And does it have to be the kyb shocks?

It does not have to be kybs. The key is to match the inside diameter of the coil over sleeve to the outside diameter of the strut. The spring will also have to be matched so it does not rub the coil over sleeve, but still fit nicely on the coil seat that rides on the coil over sleeve.
If the 86 shares the same suspension as the 84, you should be good. I'm not sure when the changes occurred in the rear suspension. I would not want to say one way or the other and be wrong.[This message has been edited by redraif (edited 08-05-2014).]

Nice write-up. I also wanted to share my recent DIY (on-the-cheap) coil-over mod with this thread.
The Coleman sleeve and adjuster kits mentioned in the OP aren't $101 for the pair anymore (they are now $137.98 for the pair) and they aren't always in stock at Jeg's. Instead, I found some Allstar ALL64143 sleeve kits from Amazon.com for $38.99 each (77.98 for the pair) which will fit over the KYB struts if you modify the sleeves themselves a bit (there are some raised portions inside the sleeve that need to be sanded down a bit - this can be done with a dremel and sandpaper roll).
I bought the 10" tall 325lb Summit springs for my Fiero ($83.94 for the pair).
I also bought some Energy Suspension 9.6118R upper spring pads (install between the spring and the upper strut plate) for $10.81 for the pair from Amazon.com as well.
You'll need to remove the stock jounce bumper (bump stop limiter) from your stock Fiero strut boots if you want to reuse them since the Fiero strut boots won't fit inside the 2.5" ID coil-over springs. If you want strut boots, the only thing I've found that will fit are the Bilstein "Service-7" blue strut boots sold here: http://www.maximummotorspor...over-strut-P975.aspx, but I don't think the OE Fiero jounce bumpers will fit inside these strut boots (but you can get some aftermarket ones if you want them).
My Fiero has a 3800 Series 2 Turbocharged V6 and 4T60-E automatic trans. The 325 lb rate springs seem to be a very good match for it offering much improved handling without hardly any loss of ride quality over a stock Fiero GT spring. I will admit the stock Fiero GT rear springs I was using seemed overloaded with the increased weight of my powertrain, which was producing an instability issue during hard cornering and evasive maneuvers at highway speeds.

Ryan, Thank you!
And thank you for adding the additional info and sources. It helps to know there are better cost alternatives available. If I can edit my original post with part source info, do you mind if I insert your finds?[This message has been edited by redraif (edited 08-05-2014).]
