Overbear

Somehow, I managed to snap a rear lateral link in half. No, not break off the end link tab, snap the whole thing in half. Anyone else ever seen that happen before?

Oh well I was ready to drop my STI ones in place anyways.

How big of a swaybar and how steep of a curb?

I thought you said you were loosing weight...

Will Whiteline adjustables give you more setup options than STI?

25mm cobb and no curb. Snapped clean in half driving down the road. Looks like it might have had a flaw, inside was rusted some, so might have been a bad weld that leaked some moisture in. We will see soon as Mert pulls it.

quite a bit more but I had the STI's already.

Flaw or it had cracked and split over time?

If cracked and split over time, I know I'm preaching to the choir with you on this one, but check other stressed areas for fractures...

Broke while unstressed... interesting. I wonder if it was preloaded and vibration killed it.

If you are in the area... get me the broken part. I'll have my dad do an X-ray image of it and see what failed.
My dad does lots on non-destructive testing for Lockheed.

Sitting here thinking about it, It did snap right next to the reinforcement tab I put on it for the heavier sway bar.

Back years ago before whiteline came out with with their endlink tab reinforcement kit. Someone on subaruforester.org made some very nice milled aluminum ones. I am now wondering if perhaps over the years of hard driving, autocross and a few track days. The stress placed on that point caused the bar to fail.

we will see once mert gets it off and I can get a good close up look at it. It may be that the rust I saw, was from a slow crack forming.

Post pics of you can.

If you look close, you can see rust where I think it cracked and started the problem

Wow. Right at that bushing... I'll go with who ever's theory about the stiffer sway bar

IMO looks like that link support plus the oversized sway caused a stress crack (which is where the rust came from). I use the goofy looking whiteline support brackets that spread the load a little further out. The idea is to stop the link attachment point from spreading inward without moving where the stress is applied to the lat link. That clamp style one moves the stress from where the actual pressure is right to the point where you cracked it because it went from the supported part to just bar (where there is no bracket) without spreading the load out, and we know those stock lat links aren't that strong. That link support clamp isn't a good design. The whiteline looks cheap, but it works.



STIs shouldn't have that problem.
