Interesting RB endlink failure
So I did an HPDE last weekend at Sebring, car handled great, drove great no issues.
2 days ago, I heard a really bad clunk from the driver's side suspension, and felt something hit the floor of the car. Thought maybe I hit a rock or something on the road, I stopped and checked it out as best I could and didn't notice anything. No adverse handling effects at all.
This morning I was just doing some standard tinkering looking over everything and double checking my pad wear.
I found this:
So from this it looks like maybe the endlink was overtightened? Caused the middle support to break? Anyone have thoughts on how this could happen? I'm going to call around on Monday to see if someone can just sell me one, instead of a replacement set, the other side is fine.

Got it. That is most likely what happened when I look at it closer. It also sucks haha. If I can't get RB to send me just one, I'm buying the 949 endlinks for sure, should have just done that to begin with, I didn't realize there could be issues with the poly bushings.

Your options: Buy a pair from RB and keep one as a spare. You'll never need it. OR go to a lot of trouble to just buy one and then the other, previously non-broken link will break within months.
Seriously though, RB endlinks are great and awesome and my favorite ever. On the street. For track duty, they're not that robust.

Never seen NB ones, but to install a RB endlink in the stiff hole as seen above is the devil's work. I'm surprised mine haven't failed yet, but when they do, I'm sourcing 949 endlinks as a replacement.

I never knew how much my bushing type end links were binding until I replaced them with 949's. It was night and day. My suspension moved so much more freely, it was compressing more and I suddenly had tire rub on my shock towers while braking!
