Almost all products are mirrored or produced off of something that already exist. Why spend 1,000+ $$ on something you or no one else will ever see, especially since there is now a comparable option for sale at a much more competitive price. If I can have a product that offers the same features, warranty and design appeal for half of what everyone else has paid for an similar part, why wouldn't I. I'm just trying to save others diving into their suspension some $$. If you want to hold fast on that $$ that was spent on the SPL part and make yourself believe it was worth it that's fine too.

Hi Smokey, your car, your choice. I have no issue with you promoting the Z1 arms. However, relating to suspension matters, the above sentence is very wrong.

TLDR: people buy SPL for the highest assurance of A) arm not snapping in high loads and B) alignment remains during high loads. There’s no guarantee, but some rather pays extra for a higher assurance. It’s like buying a car with best safety rating.

Long version: quantitatively / objectively speaking, there’s no evidence that GK Tech or Z1 FUCA are inferior. After all, the designs are the same. Spherical bearings likely wouldn’t cause any catastrophe.

So what else? That would be the welds and the metallurgy. Those are the spots where if fail, aka if arm snaps, car instantly becomes completely uncontrollable since we can’t control the wheel’s direction any more (two cases in this forum, one on track, one during a mountain drive). Does anybody have any real evidence Z1 or GK Tech employ inferior source of metal, or inferior manufacturing process? No.

But, this is where the SPL history comes in. In the lack of quantitative evidence, we look to the history of quality production and motorsports. SPL specialises in suspension parts, and their parts have longer proven history than others, and this is unquestionable.

For that higher assurance, some of us chose to pay the higher price. Few hundred bucks more is well worth it if you know how bad things get when a suspension arm breaks.

I appreciate your well thought out response and understand the acceptance of SPL and their parts on this forum and in the Z community as a whole ! Again I was very simply posting to inform others of another option that many may not know has become available. Even if one decides on the SPL parts(which is fine) I believe Z1's offerings deserve a look, that is all. I am not even a big Z1 fan as I have and am running parts from other manufactures on my car !!

If I have an issue with these FUCA's whether through operation or some type of failure, I will be sure to update this forum with those results.

It's simple. Because those companies are the ones that innovate and create new products unlike Z1 who copies companies' stuff. When it is time to innovate again, I highly doubt it is Z1 who does. They will just copy somebody else again.
