Just had a faliure on my Z1 upper control arm drivers side street version.
the ball joint hemi joint?came apart. luckly I was driving very slowly when it came apart so I didn't kill my self. Just happened in the last two hours.
We will see what Z1 says!

Let's hope z1 steps up and fixes this issue asap before something seriously goes wrong and someone has a wreck.
Since it's a big company, I'm guessing it's not really on the top of their to do list. Hope they prove me wrong and contact everyone who got these poorly built product and does a recall or something.

Just talked with my shop the bolt that holds the heim joint/ball joint together backed out it did not BREAK.I am having them use the revised type of locktite and new torque spec per Z1.
Locktite 271 torque spec 57ft lbs.
we will see if this keeps it from backing out again.

Anyone ever have these arms then go to SPL? I'm curious to see how the SPL arms differ in physical dimensions over the Z1's. I'm at the alignment shop now and the design of the Z1 arms just doesn't allow enough suspension travel when the car is lowered significantly like I am on coilovers. My fender lips are just about 26" from the ground in the front. I actually had one of the ball joints snap in half on my control arms and now I see exactly why.

Z1 sent me out a replacement ball joint over night, but I'm thinking just the design of these arms aren't meant for the G37x sedans. They physically fit of course, but the angle of the ball joint needs to be pointed further down. My alignment shop and I also just verified the arms are installed 100% correctly.

That sucks bad. I'm a little over 25.5" from the ground on my front driver side and have had the Z1 FUCA for a few thousand miles. Can you take some pictures of the brake? Which hemi broke? Was the arm impacting somewhere? I would like to see if the same future is laid out for me. At least Z1 acted fast to get you a new joint.

I had to raise my car up a good 3/4" so the car is safe. I must admit the car drives 65783168510x better now that it's been raised a bit and has a proper alignment by a shop that truly understands suspension.

Ah, now I see what your talking about. They need to adjust the knuckle mount point to be more conclusive to lowered cars, issue a high-misalignment spacer kit, or figure out something else.
I just went and looked at mine, now knowing what to look for, and the angle is almost maxed out on the drivers side and nearly maxed out on the passenger. I will call Z1 today. There is little in the world that will make me raise my car unless they are going to pay for the corner balance I would lose and the re-alignment. Since I'm only an hour and a half or so from Z1 I will try to work something else out.
Thank you for bringing this to our attentions, its an important thing for people with lowered cars and these FUCAs to know. I do not see how it would be AWD only thing. Yes, our FLCA is different and we yet a driveshaft and a different yoke for the front shock but all the upper front suspension parts are the same to my knowledge.

I'm surprised you're not more maxed out than that at your height. What coilovers are you on?
