I know Tein Basic is pretty basic as its name stated, and i am sure a lot of you guys have adjusted the ride height of your cars(with any coilover i guess). But For some reason today no matter how hard i tried, I just can't get the lower plate moving(the plate that's sitting on the spring, aka the SOB. the upper plate moved up rather easily). so do I need to release "THE BOLT" at the bottom of the shock and to free the spring in order to adjust the lower plate(SOB)? Since i don't have a lot of tools, releasing THE BOLT at the bottom of the shock might be hard because it's behind the brake. ps* i do have the pair of adjusting wrench from tein





Thanks for your attentions here! All advice are welcomed! and of course, HAPPY NEW YEAR !

 

maybe cause you had the shock on backwards?

I never had such issues

 

Hmmmmm

 

REALLY?!? I didn't notice that, STREET IMAGE (kinda famous in my area) did the install... so the TEIN sticker on your shock isn't facing the same direction as mine?

 

I'm sorry it is on the right way.
If you put it in the other way the other supporting arms will be in the way.

I thought you were trying to say that the bolt that holds the shock was hitting the spring perches.

The top collar is easy to move but once you decide to put more pressure on the spring the lower collar will become harder and harder to turn.
Thats why the key has that lil square cutout so you can put a socket wrench in it to put a little more "English" when turning the lower collar.

If you want to make things easier you can take out the bolt that holds the spring bucket and drop the bucket therefore lowering the tension so it will make it easier to turn the lower collar so you can raise the car.
Use a jack to put the spring bucket back into place and then put the bolt back in reverse order.

 

so i still need to give it a hard yank at the lower plate right? today i wasn't using too much strength afraid i might strip something

 

My Tein CS are so hard to adjust height in the rear. It's almost worth taking them out to raise/lower. I did it the other day and after about 3 turns I wanted to die...

 

Yes, you do need to disconnect the lower rear dampners and allow the suspension to drop and while your at it on reinstall but the bolts in so that the heads are pointing to the front of the car, not the rear. The fact that you could not move the adjustment spanners means you have enough pressure from the springs to cause the seats to freeze in place, releaving the pressure will allow the spanner to turn.

 

The spring is too loaded up and applying to much pressure against the adjustment ring. Take the load off the spring by doing what the guys said and then adjust it all the way to top (lowest possible). You will be able to adjust it at that point with full load on the spring.

This is what I did.

 

I haven't really played with the G35 suspension yet, but had experiences with previous cars with coilovers.

Is it possible to push down or jerk the suspension further down while someone else turns the the lower collar? Either that or jack up the other side to free up/even out some suspension travel.

 

Not possible on this platform because it's the length of the rear shock or dampner that stops the suspension from going beyond a certain point, try as hard as you can, all your efforts won't make the shock extent more. Also menas if shorter shocks are used in the rear, you will have greater spring preload.

 

It's a PITA with flex's too. I use a flat head screw driver and a hammer to adjust the collars. Especially for the front set. Stick the flat head in a groove on the collar and hammer away.

 

^ that is a good way to jack up the collars. I suggest a lot of wd40 on the threads a take the pressure off the spring and turn it freely

 

cant you just jack it up on one side and just loosen it up that way?

 

No

As mentioned above their is too much pressure on the spring. Unbolting the shock/dampner will allow the control arm to drop down and release enough tension to allow the spring seat to turn.
