i recently installed tein flex coilovers. i set the height by the recommended settings from tein, which is a 25mm distance from the lower shock lock to the lower spring seat lock. i didnt notice hardly any drop and i can't find how much that actually lowers the car. i couldnt find it on teins site and couldnt find it by searching on a few forums. anyone know how much the recommended settings actually lower the car?

i lowered the car even more today by making the distance mentioned above 35mm as shown in the pic below. any of you with this setup know how much you're lowered and what the distance is between the two locks that i've got shown?

thanks for any help.

 

I don't know an answer to your question, i do like what appears to be an easy setup to adjust a cars height. Can you tell me more about what you did and much it cost to get parts and installation, if you don't mind.

 

i installed the coilovers myself so installation was free. parts were ~ $1650.

anyone else?

 

I was wondering about how long it took you to install the set? Any welding or cutting necessary? Also did you have any problems with camber? Or add anything to adjust the camber? Thanks,

Nick

 

I set mine to the recommended settings:



I have a G35 coupe, so it sits higher than the 350Z so maybe it dropped more than yours. Here is my drop:

 

Also, if you drop the spring perch too much you'll get clunking as the spring loses it's preload. You may have to undo the lower control arm and spin the lower shock body up so you don't change the preload.

 

probably around 2 hours. really easy install considering no spring compressors are involved and the rear uses shocks instead of struts. i just installed them so i havent gotten a chance to go to an alignment shop. so i have no idea how the camber is right now.


i set mine to the recommended settings at first. i road around for a couple days to see if they would settle at all, but they still seemed to not drop as much as yours. so i adjusted them to 35mm in the D section of your pic instead of 25mm. i'm trying to figure out what drop the 25mm setting gives.

i've also read that you arent suppose to drop the car too much by raising the lower spring seat. i just didnt know what other way there was of adjusting it.

thanks for the reply.

 

here's a pic i just took. the front is set at 35mm and the back is still at 26mm. maybe i'm just not seeing it right, but it doesnt look as low as it should be.

 

It does look pretty high. Not sure what a Z is supposed to look like, though.

The lower green part of the front shock is just an empty tube, the black threaded part is the shock itself. Raising or lowering the green part adjusts the height without affecting the spring preload or piston travel. I would put everything back to the recommended settings, then only adjust the height with the lower green part by loosening that single lock nut and threding the green part up.

If you get an idea of how many inches lower it needs to go, you can probaly get the lower green part at the right spot (measurement C) the first or second time.

My install took way longer than 2 hours, more like 1 1/2 or 2 days (I did the brakes at the same time). Pulling it all apart the first time eats up lots of time, and the EDFC is a pain.

 

cool... i'll give that a try once it stops raining. thanks for the tip. i had no idea you could adjust it that way. all i've ever owned were struts and springs, never coilovers. i bet the lower green part somehow threaded itself down too far while i was handling them. i noticed the bottom part spinning, just didn't think anything of it. i'm sure that's what happened.

i got everything installed pretty quickly. i haven't gotten the edfc yet and i'm used to taking apart suspensions. the first time i installed struts/springs on a car it took me about 6 hours.

again, thanks for the tip.

 

No problem good luck

 

You said that you had installed the brakes at the same time, i was just wondering if you had added toe and/or camber adjustment parts. Another question i had was after you install the suspension, does it require a specialized shop to get the alignment done? Thanks for everyone's help.

 

I have not added any camber parts. I'll get it aligned in a few weeks and see what the numbers are, I have visible camber so it may need to be dealt with.

I know of a good alignment place that specializes in lowered cars, so I'll be using them. If the shop has long ramps that can get the car on the jig without scraping you should be fine.
