I think you are right on the money, went out and checked the RR trailing arm and the bolt was broken where it attaches to the frame. I took a big hit when the car backed into the wall damaging two rims, left rear shock, rear panard bar and suspension parts on the right front. This is the second time this bolt has broken in six races, any idea why it is breaking. All bolts have been grade 8 and the rear end is a double shear.
Thanks for the feedback,
