 Cool write up on custom coilovers

Ive been crawling around the net looking at some various supension guides and products all afternoon. I came across this article which looks pretty interesting.
Its specific for the AE86 but I dont see why it couldnt be used for a whole heap of difference cars. 
I havent read through the whole thing yet but its got lots of old school mechs and stuff so they look like they know what theyre doin. 
Anywayz, check it out!

sorry but this is old school
their basically for short strokes such as the HTS and the trd's, hence why you need cutting them!
but yeh, great read. I've got a printed version, basing my conversion on these!

bestest reason for posting a thread EVAH 
so they didn't even weld the top and bottom half of strut together and are just relying on the tack welds to the sleeve to take all the upward force or the shock? eeek

Hm, i thought that they welded the strut casing back to gether then welded the sleeve onto that? .. oh well
Yeah this guide was pretty good explanation on WHY and HOW with short strokes..

yeah, im doing this conversion for my car. i also queried the point where they didnt weld the strut back together. i thought that was the only real weakness in the setup. apart from that, i though it was a really well done guide.

yar i thought so at first, but in the pic where you can see inside the strut casing, it looks like either it's not welded, or it has no penetration to the inside... sinc ethey have alot of other pretty pics, i would have thought they would show the grinding back of the weld to be able to it the sleeve over after..
heh heh, methinks the WHY is what escapes most people, and how to calculate the actual amount of drop needed.... most people don't even need short stroke shocks (and probably shouldn't have them), and would be better off with long stroke shocks...
the diagram there gives a head start i suppose.. but with the short strokes, you have such little travel left that it is absolutely critical to set it up right..
not much point having 30% bump instead of 60%, but thats only a couple of cm difference..

you are right, you only need short stroke shocks if you want your car to have hard springs and dont want it to sit any higher than standard. 
better way to do it is get new thread cut, but if one of the Clampets welds it back on then that must be fine too.

That "line" you can see in the inside is actually a machined lip to allow clearance for the "sleeve" on the nut that helps locate the top of the shock insert. The actual join is abou 2" lower down, abou half way down the threaded sleeve. While i would weld this join myself, i have spoken to a couple of 86 drivers in Improved Production, and they only rely on the welds top and bottom of the sleeve. One of them just welds about 50% of the circumference (2 welds of 90 deg), the other welds the full 360.
My preference would be to weld the "inside" join, and the top and bottom of the sleeve, for the entire circumference.

I would also like to find out as to who those two IPRA runners were who dont weld their entire struts. Certainly doesnt sound like the professionalism displayed by the AE86 IPRA runners in NSW that I know....

there is a downside of fully welding the struts you know, the HAZ will go the full circumference of the strut, if stitching is strong enough, then thats all you need to do.

A MATE whos A fitter machinist has a rx7 s1 with hard rate low spring in it; any ways to lower the shock he simply cut the top of the shock off & tapped a thread in it put a stud in it and merry x/mas a lowered shock: i know its mega bodgy but it cost him nothing except time at work it and now the springs are trapped for registration
