A brace wont help this problem either, because it wont stop the belt putting pressure on the pulley.
Drive on tarmac or other grippy surface long enough and use the brakes well and you will see what I am talking about.
Don't know what to tell you man. Myself along with others have given you several options to prevent the belt from getting off track. You're the first I've heard of that had an issue that wasn't resolved by one of those options.
EDIT: Sorry for the "late hit" I reply as I catch up on the thread.
PS: If you bought the RTR thinking that it would win races straight out of the box I feel for you, but you can never expect for that to happen with any RC model I know of. I wish AE would stop making RTR's all together as it's misleading since it's not a good brand for that type of user.
