Stock parts can easily break and can wear easier over time. Bashing and high impact crashes can damage plastic parts, while these upgraded parts are made of aluminum and will fare better under impacts. Some stock parts like the shock towers are already made out of aluminum, although they are very thin. With a thicker shock tower, bending is prevented, especially in the case of a roll over. The aluminum is not only strong, but very light, so these parts will not weigh down the model significantly, which is very important for those who want performance and strength. Many parts are available and most come in four anodized colors. Please take your time to make sure these parts will work well for you.
