Optimal viscosity selection is a balance between ensuring the oil flows easily during cold starting and maintaining sufficient oil pressure at maximum expected oil temperatures

This is the shorter gear ratio of the two available options and was used on USDM STI MY04-06 and all JDM STI

Final Drive Gear Set R160 Gear Ratio:Ratio 4.11 Also controls diff movement andFinal drive gears, also known as ring & pinion set or crown wheel & pinion (CWP). For Subaru R160 applications (160mm ring gear OD). Ring and pinion gears are a matched set. Professional installation is required for best results. Setting the correct pinion depth, backlash, and bearing preloads is essential for maximum life expectancy and minimal noise. Select appropriate rear diff ratio. Ratio must match front ratio and transfer ratio otherwise center
