This picture is extremely telling as to where the point of failure was. As you can see, the control arm material that the endlink bolts to is still captured between the endlink and the endlink nut. It's reasonable to say that in the cases presented so far the sway bar bracket is working much harder than originally intended. Had the bracket been fatigued by a loose nut, we would have expected that the area around the hole in the bracket would have elongated and then broken, instead of torn completely away. Now that we are seeing this failure on stock as well as modified cars it appears clear that for some extra insurance, a reinforcement designed to redistribute some of the load from that bracket is necessary.
After some discussion we are going to be selling a reinforcement bracket prototyped in earlier in the thread.
Initial purchase price will be 30.00 per car, which includes brackets for both control arms. As seems to be the case with everyone these days we are extremely busy with both our Corvette and Camaro product lines, but we will be able to provide these production ready support brackets in about 4 weeks.
Stay tuned for more details coming soon as manufacturing progresses.
