Get Better Performance From Your RC Car
Know the purpose for which you want to soup up your RC car. If it's for a race, check to see if there are regulations prohibiting certain types of car modifications, such as turbochargers. If it's for casual use, define what you're trying to accomplish. Do you want your car to accelerate faster? Become more aerodynamic? Have better handling? The specific reason you're souping up your car defines exactly how you will soup it up.

Head to your local RC hobby shop or go online to search for the parts needed to make your modifications, and to get advice on better ways to install them. Bear in mind that costs can add up very quickly as you gather all the necessary parts to soup up your RC car.
Read absolutely all instructions that come with the components you procure to make your modifications. Understand them fully and completely before attempting any assembly.
Test out your modifications before completely re-assembling the body of your RC car, if it was necessary to take it apart to install the new components. This can save you a considerable time in the event you need to tinker further to get things right.
