The AVID RC8.2 Carbon Rear Chassis Brace Support AV1803 is designed to help prevent the breaking/tearing of the stock molded RC8.2 brace which is used in the RC8, RC8B, and RC8.2. The molded brace offers the best performance for the vehicle but due to brace having a 5 degree angle placed in it to help clear the radio tray, it can be broken from very bad crash.
