mmmm
My kit is fairly new raced it only twice and I managed to break the Nerf bars in those two races! So it seems effective! hehehehe
Actually, my fellow racers here say that if your car breaks easily, you will become a better driver, because you will lose your affinity to those unfriendly bariers 'cause parts are not cheap!!!! and you will know which lines to take! thus becoming a better driver in the end!!! hehehehe
Peace!!
