I have Tein monflex coilovers installed and I just recently installed the SPL mid-links with Tein racing springs. According to Tein.com, the coilovers lowered my ride height to (before the mid-links and with stock wheels):
(F) -0.79" (R) -1.18"

According to SPL the stock ride height for the 350z is 26.6" which I'm assuming is front and rear since he never mentioned otherwise. Can someone confirm the stock ride height?

My problem now is that my ride height is totally jacked up since I installed the mid-links and I don't know how to get it back to an optimal adjustment.

I also have the LMGT4s mounted with (F) 235/40/18 (R) 255/40/18.

I took measuring tape and check the height from the floor to the top of the wheel well:
(F) 25.56 (R) 27.5

The front height is more or less how I want but the back is too high. I basically want the same stance I with the Tein monoflex. Can someone help me out?

 

that would be some good info because I need it as well hahaha and I pretty much have the same tire size and wheel size as you do

 

The stock ride height is 26.8-26.9" front and 27.6-27.8" rear.

I am assuming you have the mid link perch adjusted all the way down? What spring (spring rate/length) are you using with the midlinks?

 

Kauh,

My perch is adjusted towards the top (according to the instructions), the springs are Tein 780lbs, 7 inches.

You said the right height is 26.8-26.9" front and 27.6-27.8" rear. Is that with stock 18s(or 17s)and 45 profile tires?

I guess what I'm trying to ask and really trying to do is get the ride height closest stock specs of my Tein coilovers.

 

Once you start adjusting the perch down, your ride height will drop... we recommend starting with it all the way up because it is easier to adjust the perch down than to try to thread it up.

Correct... with stock 18" 45 profile tires, the stock ride height is 26.9" front and 27.8" rear.

 

your ride height is going to be different with you running front tires on the back of your car
