ABSTRACT An attempt was made to compare the aerodynamic forces acting on Subaru WRX STi version IV (SPC) with a recommended World Rally Championship (WRC) and a non-recommended GT Wing Type-A (GTA) spoilers. The experiment was done with the following combination, SPC, SPC+WRC (REC), and SPC+GTA (NRE). The above experiments were carried out at a Reynolds Number (R) range of 2.19 x 104 to 10.94 x104 and an angle of attack () of 0° to 20°. The lift coefficient (CL), drag coefficient (CD) and side force coefficient (CS) are computed from the measured data From the analyzed data, it was found that, for REC. CL decreased in the almost all the investigated ranges of and R. The maximum decrease in CL is about 40% (at = 20°). On the other hand for NRE, CL increases for almost all the investigated ranges of and R. The maximum increase of CL is about 177%. At, 2.19 x 104R6.57 x 104, there is little or no changes in the value of CD for REC and SPC in the investigated ranges of . It was found that value of CS for REC is less than that of NRE in the investigated ranges of and R.
