I also considered the SPC adjustables but after seeing photos of two failures in the last six months,and the aftermath, I've decided to go with UMI control arms.

Do you guys recall where the failure was, and what the circumstance that caused it was? It's one thing if a part breaks in a wreck, it's quite another if the failure "caused" the wreck. I remember years ago that there was a knock off on the SPC arms that was seriously under-engineered that I wouldn't trust under any circumstance.

One failure was posted here and did not involve an accident. It would be good to know the root cause. Failures can be caused by many things, including improper installation. I cannot remember the thread name or who posted it.

I will take a look at the UMI parts.

According to that thread the issue was incorrect assembly of the SPC upper arms. Not only were the upper pivot shafts installed upside down, the ball joints were also installed incorrectly.

I can't see a picture of where the arm actually failed? I did understand that they were incorrectly installed, but not clear what specifically failed. Did I miss something in the thread that stated what actually broke?
