Shock shafts can break rather easily but mostly because they are mounted on the front of the arm. so when you bump another car hard enough it may hit the shock shaft and not the bumper. I stopped hitting stuff and the problem went away. In 3 years I only had one front shock tower crack and one front top plate start to break. So I would say it's a pretty durable car to begin with. All the mods will just make it even better
