Project details

Due to the popularity of APR's 2004 SEMA project, the APR EVIL-R Widebody Mitsubishi Evolution, APR Performance has selected the Subaru STi as the next addition to our widebody aerodynamic kit selection.

The APR Performance SS/GT (Special Stage/Grand Touring) aerodynamic widebody kit offers traction gains to Impreza WRX and STI owners. The SS/GT aerodynamic kit increases overall body stance by 3.15 inches (80mm). With this increased distance, Impreza owners can now run 18 inch wheels with wheel diameters ranging from 10 to 11 inches and tire diameters up to 295mm to maximize wheel traction.
