Does the chassis guard work?
You can clearly see that there is no protection under the engine. Parts such as the engine and exhaust pipe are exposed.
There are generally three kinds of materials, composite material, aluminum, steel engine. General classification for composite material is the best, followed by aluminum, the most for steel. What's the danger? First: the mud splashed when driving will paste on the core parts of the car, over the years will cause corrosion to the parts. Second: usually driving will often bring small stones, driving these small stones, sure will break what small parts. Third: we usually drive will have chassis rub or even "bottom" situation, at this time if the engine and other components exposed is very dangerous. Once the chassis bottom scratches seriously, it will scratch the oil pan, oil leakage, and eventually lead to engine cylinder pulling.
