I was running lightweight aftermarket toe arms with anodized bearings. Even though the corrosion was starting to show (I've had them on for about 7 years now), they still moved freely and were set up fairly neutral without binding. Not sure how but the inner bushing housing snapped. Going with Whiteline rear adjustable toe arms this time.

And this is why I'm not a fan of running aftermarket suspension links/arms/primary structural components. Almost never necessary, and nowhere near the level of analysis and testing as OEM.

There are aftermarket companies that do a thorough amount of testing, though. Versus Engineering is a good example. Their aluminum rear LCAs are far lighter than stock, and look far flimsier, but they did lots of FEA and testing to ensure they are robust enough to stand up to abuse, and as a result they've been on my car for over 6 years now, and have seen endless Chicago potholes, seasons of autocross, and even some VERY violent impacts with road debris.

You're right, though. There are plenty of companies that do NOT do that kind of testing, which is why buying those kinds of parts requires actual research and not just blindly buying whatever is cheapest or on sale at the moment.

No pics? no brand name to help us know what product failed? Glad you managed to avoid a catastrophe but help us avoid the same with better info

Hardened steel or aluminium? Did the bushing housing snap? Or the adjustable stud?

I'm running RSR coilovers and LCAs but the toe arms were Versus.
