Chassis preparation is similar to a road racing car. Roll cages are sometimes employed for safety, and to improve the torsional rigidity of the car's frame, but are compulsory in events that involves the 2+ cars' tsuiso runs in the event of a side collision. Front and rear strut tower braces, B-pillar braces, lower arm braces, and master cylinder braces are all used to stiffen the chassis. The interior is stripped of extraneous seating, trim, carpet, sound deadening; anything that is not essential is removed to reduce weight.
Body kits are often attached with cable ties. When the body kit meets the wall or curb, the cable ties snap, releasing the part, as opposed to breaking it.
As drift cars are pushed faster, aerodynamic tuning becomes more important as well. Rear spoilers and wings usually are useful only in large, open tracks where the cars develop enough speed to create a need for more downforce. Wheel arches are often rolled or flared to allow the fitment of larger tires. Airflow to the engine is critical, so the hood is often vented.
Due to the nature of the hobby, drift cars are typically involved in many minor accidents.
