Tein Flex Z Preload Help!

[trinidadj]

I just picked up some Tein flex z coilovers from another member on the forum. I'm going to be install them this weekend. I wanted to know if anyone had the instruction manual. In particular I'm wondering how to adjust the preload to the factory settings or check it?

Thanks for the help!

They recommend to turn the preload until it's "tight" then one more turn. Ymmv

like typer said. but i tightend little more than default.

The thread pitch on the collars is 1.5 and the recommended preload is about 2mm? So, with the collar tightened right up against the spring, another 1 and 1/3rd turn will get you about 2mm of preload. Check preload again after a week or so then do the process again.

Thanks for the help so far everyone! Should I worry about adjusting anything with the camber plate or just the let the alignment shop handle that? I'm also going to install some lower control arms so any tips on setting camber for those? (lower controls will the whiteline lcas not the spc re-branded ones but the original beefy ones they made in goldish color pictured below)

Also I'll be running the stock wheels/tires so how low can I go with tein flex z coils and lcas before needing adjustable front end links and rear toe arms?

Match the length of the OE LCA's as close as possible, if you do then your alignment should be relatively close to what it was before you put them on allowing you to drive the car to the shop safely.

Be extra careful driving it to the shop, you may have made the car a bit unpredictable if you aren't close enough.

You will not need rear toe arms, OE is perfectly fine for any sane adjustment.
idk about the front swaybar endlinks but I don't see the point in slamming the car so someone else will have to tell you.

Okay thanks for the response ill be sure to measure both. I'll be on stock tires/wheels and I'm looking to drop the car to the factory height of 1.3" that the tein's come preset with. I would like to have -1.5 degrees of camber up front and -1.0 in the back (or should I go more i'll just be DDing for now). Also does anyone have the instruction manual for the tein flex z that shows the factory ride height adjustment? (Like those A,B,C,D positions and measurements). I cleaned the threads and doing so moved the locking collars and base to various positions.

you can go online to tein's website and they should have all their manuals available to view

I can't seem to find manuals on Tein's US website. Can you give a link?

[trinidadj]

I'm having trouble locating them also. I swear I've looked everywhere!

Thanks for that info I did actually come across that while browsing the site. I'm really looking for the diagram that has the factory collar measurements like the one pictured below(this is for a totally random car have no idea!). If anyone who has the manual will you please snap a pic of those diagrams or list the data out. If it is available online will someone please point in the right direction. I'm looking to install Saturday!

I slightly increased pre-load from default though.

between 2nd collar ring to bottom collar, it's 28mm on front and 35mm rear.
when i lowered mine, front gap seems little higher than rear. try 25mm or 26mm at front and should be looking similar to rear but i havent adjusted anything yet. lol

I have sti lips around and front lip still doesnt seem like very low enough to scrap anything but if i lower 0.5 inch more, i would scrap everything..haha

After searching I was able to find this. Thanks to zc06_kisstherain.

I'm going to take a pic of the coilovers with a drawn diagram showing the measurements between collars. Please still post the diagram and table if anyone out there has it.
