Height Adjustment

Yes he is. That’s how mine looks at minimum preload. I suppose I can’t speak for him but I’m at “max low”.

Removing preload and lowering the spring perch would get you lower, but you would sacrifice some bump travel.
I’d hardly consider a 3” drop “super low”. At best I’m getting 1.75 - 2”. Like I said I still have a full finger of gap at max low. Preload is basically zero on my setup.

This seems more likely what might be wrong... I'm having a hard time imagining the change this would make though. I would set the preload on the perches before re-tightening into control arm, right?

Sure, but I’m wondering which component was seemingly changed somewhere in the manufacturing process from the older ones to the newer ones.

"minimum preload" means nothing, you can still lower the spring perches and achieve a lower ride height.

If they insist on maintaining the same "preload" then that will have no change to ride height and only create a risk that the spring binds. A stiffer+shorter spring and maintaining "preload" will raise ride height.

I didn’t know you could lower the spring perches. I’ll have to look into that.

One of the big thing that Tein advertises about the flex series is the ability to change ride height without messing with preload. Hence the perch adjustment.

Just get a LCA with the different mounting points. PBM is a good option.

Oh wow only $240. Not bad at all. I guess I’ll just sell my SPC ones. The 25mm setting would be perfect.

I'm having a hard time finding any info on how to do this. Manual doesn't say anything and searching isn't finding me anything. Any idea of any resources?

FULL LENGTH SYSTEM FOR RIDE HEIGHT ADJUSTMENT WITH MINIMAL CHANGE IN RIDE
Full-length ride height adjustment system, used for FLEX Z, enables adjustment of ride height by adjusting the case length, without changing the damper stroke length and/or spring pre-load. This has the advantage that the change in ride quality is kept minimal when the height is adjusted.

This system not only makes it possible to maintain good balance between the low-down appearance and ride comfort, but also provides more setting choices for sport driving as well.

Substitute Z for A. Same wording otherwise. It's in their advertising and what everyone is referring to when saying adjust the spring perch instead of messing with the preload. I don't have the manual in front of me.

Okay but I can't find anything on HOW to do it. I know how to unlock the lower collar and screw the body into the lower housing (which maxes out), I know how to adjust the preload. What I think you guys are saying is I can lower the upper perches (that normally adjust preload) without removing preload, which I don't know how to do.

ya'll got it all mixed up.
two ways to lower it.
1. as the manual suggests- bottom mount, keeps preload and adjusts the case length.
2. Spring perch, which also affects preload. Not suggested as spring will not be captive under full droop and it will affect bump travel.
option 3. buy lower control arms with different mounting points.
option 4. buy another suspension setup.

No, after further lowering the spring perch there will be "zero preload" at full droop the springs will be loose.

This is really not as problematic as it's hyped up to be. For instance all of RCE's Tarmac setups have springs that would be loose at full droop without the tender springs they include in their kit. Those have "zero preload" and there's nothing terribly wrong with that.

Thanks guys. I was beginning to think there was some miscommunication with NoHaveMSG. I retightended bolts under weight and I think it helped a bit (more so some turn stability/return to center issues I was having). I'm perfectly content with the answer "they just weren't meant to go lower." I was more just worried I did something wrong since the front would go so much lower than the rear. Thanks for your patience and help!

Sorry, I didn't give you any reference as to exactly what I was referring too. It just sounds like for some of you guys these just don't go low enough. My car is only dropped about an 1.25, as someone who came from the motorcycle industry I found the preload/height adjustment setup rather ingenious.
