Let me start this post by making it clear: I don't have these.
However, the design looks exactly like the Kinetix ones, which are absolute garbage. Hopefully they're of better quality. If they're not, good luck to anybody using them.

that was my first thought as well that they were surprisingly similar to the kinetix one just with a different coating

Why do you say the Kinetix are garbage? It looks like the Kinetix are alloy steel and the new Z1's are moly. I definietly would have liked to see some gusseting at the bends on the Z1's.

I bought the Kinetix when they first came out. I took them out of the box, inspected them, and sent them right back. Flimsy light gauge metal. The welds are not excellent, which you'd want for a suspension component. To adjust camber you screw the heim joint in our out. So the strength in the weakest area of that part (the middle) isn't a constant and it seems pretty weak with it screwed out to a normal amount of camber. The design itself is pretty noisy, especially the race ones.
Maybe I'm wrong and these are fantastic. But for my suspension I'd rather feel more sure than "maybe they'll be OK".

Anytime you add a harder bushing material or a solid bushing the NVH is going to increase substantially. Z1 does a good job of calling that out in their description of these new arms. It all comes down to how much you can handle for how much you want to gain. I don't, however, see that as a negative if that's what you're wanting. I can't speak for the flimsy gauge metal or the poor welds, but the design itself I'm not worried about as long as the welds are quality welds. I come from the Mustang world where the same heim joint design is used on the upper and lower control arms in the rear and those things take a beating with some cars cutting as low as 1.0x 60 foot times. I know daily driving is tough on parts, but I don't see the design being an issue.

I did notice that too. Very similar but not exact. In contact with them via FB and will see what they say. Tried to ask "These aren't rebranded Kinetix?" with more tact. lol
Yes these are completely from our design and built a little heavier than the Kinetix. We have been testing development designs for over 2 years with no problems. Our test cars do see fairly aggressive abuse jumping curbing at quite a few tracks and Russell's street driving is also a bit over the top. I would say I have more faith in these arms than any other part on the market.
I guess I'll be the guinea pig. Just ordered a set. Hope to get them ASAP so I can get this car aligned properly. Ended up being $301.xx after shipping which is the cheapest I've seen for front upper control arms.
