Racing is on an all carpet track, and to be fair, the car did roll and the shock towers dug into the carpet.
Pete, can you not ask Martin at Hansell / fibrelyte if he can knock out some carbon towers at a more competitive price?
As Adam has suggested, maybe sealing the tower with superglue, and shamfering it to take the edgest off that dig in might help.
