Are endlinks that weak that they need to be upgraded when you do sway bars? Reason I ask is, I'm starting to do more auto cross and I wasn't for sure how well they would hold up. Especially since I plan to do a track event later this year. Thanks.

 

I ran my stock endlinks for 80k miles with plenty of autocross and track use on aftermarket bars. They don't hold up well on full stiff, but most people don't need the bars set to full stiff.
