X4 suspension problems

[steve-thebabystore]

Hi, driven the X4TE for 3 meetings now and broken 6 inner hinge pins. They've all sheared at the exact same point. Twice was blatantly my fault with high speed impacts but to the cars credit only the pin has ever broken and not wishbones etc.
Worst one was today, BOTH pins snapped at the same time on a run up the launch ramp? Any new batches available/replaced parts?
