The motion of vehicle in a fluid exerts a force which affects the performance in terms of fuel efficiency and speed. The drag force acts in the direction opposite of motion which pulls the body back due to the vortexes created in the spaces around it due to the formation of eddies. The nature is attributed to the formation of wake behind the vehicle in motion. To lower the effect Spoilers were introduced to reduce the area of wake formation. This study shows the effect of varying profiles of Spoilers, of varying angle of tilt and the chord length and fixing the position of its location. The result shows that the NACA 2412 reduce the drag force by -3.89N but increases the lift force significantly whereas NACA 2414 series reduce the drag force by -3.41N but the lift force remains almost constant if compared to car without spoilers.
