Tein Flex Z Help
 

Hey everyone, I recently installed my Tein Flex Z coilovers and noticed the rears were still pretty high up even when fully maxed out. I'm pretty sure these were supposed to drop 3 inches in the back and I don't think I'm near that. There is still a lot of thread left, but it wont lower anymore. I took the bottom cups out and threaded them as much as they went just to be sure. I've been searching for an answer but couldn't find anything. Has anyone else had this problem? :thanks:

I don't have this problem. My setup before is drop 1.3 front and 1.3 rear, and i barely put one finger between my wheel gap. Even I use Tein recommended setup now is still smaller gap than yours. (0.8 front and 0.7 rear).

That's weird. What's your wheel/tire setup?

Are you trying to lower it? Your perches are set higher up.

Yes I'm trying to lower it a lot more. I never touched the spring perches I just left it factory spec. Wouldn't altering the perches increase/decrease preload?

If the threads are maxed out, next thing would be rear LCAs. The slight tire stretch makes the gap more noticeable as well.

So it's normal to be this high even when maxed out? I was under the impression that maxed out would be when all the perches were touching, since I have so much thread left.

Its a 255/40/17 with -3 camber, so it wouldn't matter much.
I can put 1 finger front, and about 2 fingers rear.

Yeah my rears are about a 2 finger as well. Just wondering, how much lower are you able to go?

I think I can still drop 1 inches more, but I didn't do that due to 255, it will rub.

Maxed out the front (removed the locking rings), and maxed out the rear plus using some pre-load adjustment.

Something is wrong my flex z didnt even max out on 18x9.5 +38 is only .5 inch gap i can tuck the tires my rear is -2.3

Yeah thats pretty much the same set up as me so idk what went wrong. Here's some more photo's because that angle and ground not being even might of made things look worse. Rears are completely maxed out and fronts are perfect because they have some more room to go lower. Only looking for another 1/2 for the rears.

Have you considered contacting Tein USA about this?

If the shock body is bottoming out in the lower bracket, they made a design change in production that has obviously impacted the advertised specs.

My Ohlins from 2013 were a similar situation, I suspect they used parts from another platform to reduce some manufacturing costs.

I just contacting them over the phone and they said it was my preload. Apparently this was a common problem. They gave me a link on how I should fix this so ill post it in here if anybody needs. Hopefully this works:D

You have tons of threads showing. If you want lower you want to the lower cup to move closer to the springs

you put more pre-load not height. i was thinking about samething when i saw many thread showing

Just because there are threads showing doesnt mean that there is anymore adjustment. If the shock body is bottomed out in the cup, that is the lowest it'll go. We have the same coilovers on our car:

This is max adjustment for the rear on our set.

OP, that's all we got out of our car too (same wheels too), but we had a taller sidewall tire, which helped a bit with the gap. We never bothered with adding more preload, as I dont think it would have had the effect we wanted. Yours honestly looks a little bit higher, but it could just be the different tires. It's entirely possible that the shock bodies are longer than they should be, but obviously I'm not positive. But it is a reasonable explanation for why it would be higher than others when maxed out.

I see what you mean. If the shock body is too long for those then no more will fit into the bottom cup.

Thanks for the detailed response, this makes sense now. And yeah, the tire definitely has something to do with it, these are fairly thin sidewalls. The only thing that is confusing is that the passenger side is at least a 1/2 inch lower then the drivers side, which makes me think I did something wrong.

Keep in mind the springs will end up settling a tad. Mine looked similar to yours when I first installed them and now I have in between a 1 and 2 finger gap in the rear
