Interesting. I'll have to take a closer look at them. They came with the car when I bought it.

I was thinking I'd probably end up with SPL if I do trailing arms, because I'm using their stuff for most other things (Rear LCA, rear toe links w/ lockout, front arms, and front outer tie rods). The STI part isn't much cheaper. But I probably won't mess with the trailing arm unless I get a traction mod, which could be a while. MCA isn't available, and GKTech I'm not sure if it's a good design.

Hopefully my MCS 2WNR can handle it. My concern was more about whether the geometry of so many links interacting _requires_ some flex somewhere in order to not just completely lock up and stop moving.

Yeah, poly is a last resort for me. The Turnin Concepts stuff I had on my 05 STI wasn't too bad. But all the SuperPro and Whiteline stuff I've had on multiple cars has been a bit sus.
So far, I've liked what I've seen from the SPL parts. The rod ends are huge and nice and tight. And I really like the clamp locks on the turnbuckles. It doesn't tend to shift things like jam nuts do, which makes it very easy to get the setting right, and then lock it down without changing the setting or messing up the alignment of the rod ends.
