For those of you that have switched to the smaller bearings (5 x 8 x 2.5) have you noticed excessive wear. I've had two rear bearings fail. At first I thought that my car had a severe tweak issue when cornering. When I came back to the pits I checked the chassis and everything was fine. I know that the smaller bearings won't take as much of an abuse as the larger ones so that's why I kept the stock bearings in the front and only changed the rear bearings. I only had the bearings in the car for two weeks. I can understand taping boards might cause it to weaken prematurely, however when I do TAP the boards....it's only the front. Luckily the bearings gave out during qualifying so I was able to replace it before the mains.
