Painted body kit can be built up into a complete car using the chassis and running gear of your choice. The MMK49A differs from the original MMK49 in having actual headlight detail - pockets, lenses, and clear covers, where the original just had the tape decal over the body contour.  It's not easy to see in the photos but it's there.

Body is painted in overall red color with decals included for numbers and other graphics.  Requires additional painting to complete as shown.

Need a chassis for this body?  See all the available universal chassis HERE.  In that category you will find a variety of chassis manufactured for the purpose of building complete cars from body kits.    We have tried to include in the product page for each chassis as much manufacturer's information as possible, but this is often somewhat scant.  In general, your best option is to select a chassis with adjustable wheelbase so you can simply set the wheelbase to fit the body.  Also, the narrower the chassis, the wider the wheels and tires you will be able to fit under any given body. 

Unfortunately, because of the large selection of choices offering different performance levels and price points and because we do not have direct experience with your specific combination of track layout and surface condition, power, and racing rules we are unable to "spec" a complete car build for you.  We will, however, try to answer any specific technical questions you may have.
