Curbs go brrrppp
I wrote @BMRTech an email as well as contacting Ford Sales there on Monday morning sharp about an a arm that failed under braking going into biznitch at VIR. This ultimately resulted in a good scare, minor damage to the fender and rocker panel cover, and a long story of how I got the car home.
All told, this situation went as well as it could have. had i been on the full course, it would have been a different tale. potentially with that brake zone for roller coaster.
I had run these arms in approximately 20 track events since May 2020. They had normally been run on Hankook R-S4 tires, but I have a surplus of RE71R for reasons I wont get to here and decided to start tracking on those. Perhaps the added stress was too much.
Speaking of stress, this side of the car had never been dropped off the car or had contact with another car. It had been over FIA curbs plenty but thats it. It appears to me it failed due to metal fatigue.
I am happy to answer any questions anyone here may ask to offer assistance to others choosing parts.
