Getting high power under  the hood  is not enough  to judge the performance of the car. Aerodynamic properties must be considered for the purpose of studying  the drag and stability performance of a car. In order to improve car aerodynamic drag and its stability, an aerodynamic device  is needed such as rear spoiler.  Rear  spoiler  is  an  aerodynamic  device  that  functions  to  slow  down  and collect  air,  causing  it  to  stagnate.  This  rear  placing  device  creates  an  area  of  high pressure  to  replace  the  usual  low  pressure  over  the  trunk  resulting  increasing stability. The objective of  this  study  is  to  investigate  the effects of aftermarket  rear spoiler to car aerodynamics drag and stability. Several rear spoilers design is attached at rear part of base line model. Both BLM model and rear spoiler models are built in CAD software. The CAD data then, either with or without rear spoiler are analyze in CFD  software  to  estimate  the drag  and  lift  force which  is  acting on  the  car. Force, drag  and  lift  coefficient  values will be determined  in order  to  study  their  effect  to drag  and  stability. Some  limitations  occurred  due  to  the  complexity  of  the design. From the result, rear spoiler can help to reduce drag, by creating high pressure at the back. 0aAutomobilesxAerodynamics
