making adjustable front struts.

you will need threaded sleeves, springs and spring seats. may as well make them camber adjustable up front too so buy some cheap camber plates off trademe. cut og spring seats off strut tube and then weld on threaded section/seat for threaded section and wind your seats down the threaded section right to the bottom and roll in style. probly worth getting some short as fuck shocks for the tubes and cutting the overall length down as well. this will make your slam more slammed.

jumping into shit blind is hilarious, just doit

Here's some places to buy Strut sleeves and seats

These fit on some oldschool toyota struts

more expensive (AUS) but good quality and comes with top hats

Just have to source some short ass shocks and you're good to go. Oh the struts you want to do it to has struts tubes not encased/enclosed struts right?

this maybe a stupid question but the trademe ones you have supplied a link to shows threaded tube made of alloy so i take it they only attach to alloy struts correct? the other one shows steel tube so these could be welded straight on no dramas?

Problem with adjustable height springs like that is that the shocks still determine the ride height.

Wind the springs down, and they're not captive.

Wind them up too much, run heaps of preload and have a car that handles like a bag of crap.

Ideally the adjustable section would raise or lower the shock and spring together.

Which is not to say adjustable spring perch is pointless,

What I am trying to say is that make sure that you are double, triple sure that if you cut down the top of your strut that its going to be at the right height! As the length of shock that sticks out is more or less what determines how it's going to sit on the road, assuming you dont want a car that handles like crap or is illegal.

a few more things to think about before you start, you dont want to weld to a sealed shock, this being oldschool we'd all assum you have a rwd with removable inserts so your safe? but you havent mentioned type of car

dont waste your time with alloy sleeves there a pain in the arse if you run any preload

if you want to go low then you will need to shorten the strut casing to fit a shorter (body) shock to get more travel, doing this you will have to do a dry run(ie no springs) to set bumpstop height before installing springs etc

if your going low you will prob want to make/fit some RCA's to reduce bumpsteer

Aren't keeper springs used to combat this? ie: use keeper springs to keep spring captive but not adversely affect spring rate

So this if your your corona?

Go for either steel or alloy sleeves, doesn't make too much difference in the end. Get the thread (if steel) or perch (if alloy) TIG welded on for strength.

Choose shocks, those struts are pretty similar to AE86 so you should be able to use AE92 front shocks, which are shorter and have a shorter stroke then any corona replacements you would buy.

Decide on what length you want the strut to be and where the thread will come up to, cut and shut to suit. You could make the strut the same height as the shorter AE92 shock but it would be pretty slammed if you did that, so choose where you want it to sit, cut to suit and then use a spacer under the shock to make it sit in the right place.

Choose your spring rate and length at the same as doing the thread to make sure they will be captive. 200 or 250mm springs are the go.
