Internal modifications, such as to the engine and gearbox, will usually be accepted without any inspection but more obvious modifications relating to or affecting bodywork, vehicle height and handling require authorisation. You must hire a qualified engineer to make a detailed plan of your modifications and to calculate any risks likely to be caused by the alterations. This plan must be sent to the Department of Land Transport (DLT) in Bangkok for approval. If the director of the DLT approves your plans, then it is legal to alter your vehicle but only as detailed in the application. Modifications not sanctioned are illegal and you could face penalties if caught. You should carry the approval document with you to show to police officers or any other officials who may ask to see it. That said, I advise you, for your own safety, not to modify your car at all. The vehicle was engineered to work in a certain way without any modifications.
