If it's for motorport, it will need to comply with specific quality and design regulations (which will vary depending what branch of motorsport). At the other end of the scale if it's purely cosmetic you can just stick foam tubes to the inside of the car. You may not want to go to either of these extremes, but I'd suggest you probaby want to stick to the spirit of the MSA regulations if you expect it to provide any protection.
