Blitz's RS4 features a unique center wing tower to offer better support for the rear wing, delivering superior rear end stability without losing top speed. Being slightly shorter and narrower than the RS5, the RS4 has better agility making it ideal for racers seeking a more reactive car.

The RS4 body comes in several different thicknesses. The 0.5mm body is ideal for most conditions with good stiffness transferring more downforce onto the chassis, thereby increasing overall traction.

The 0.7mm bodyshell is the strongest and is recommended for racers who want a stable handling and long-lasting body shell.

All bodies come with masks, decals and wing mounting hardware.
