My theory is that there was either a bad batch of aluminum. And yes, the rear hanger would have probably been better off with a stock setting of 1 deg anti squat and 3 deg of toe.
imo....the problem with the rear carrier is the eyelet lobe for the bushings are too low. they hit the track surface before the chassis on flat landings, actual dirt tracks they start wearing down before the chassis, when they wear even with the chassis they still hit at the same time. either way stress transfers to the thinner part of the carrier where mount point is. the carrier bends or break in a shear which is visually unique to aluminum or bend
carpet tracks, while some may think they have a carebear surface, usually concrete under the thin ozite. some of the photos that were posted just pages shows racers on carpet surfaces with the same issue
