Listed below are the PPG gear ratios for the BRZ / FRS Transmissions. The chart calculates vehicle speeds based on the gear ratio, final drive ratio, and tire size. Changing to a taller or shorter final drive ratio can customize your overall gear ratios, specific to your application. This chart is just a guide, as other factors could affect your end result.

 Note: These gears and final drives are available for sale HERE.  We can also build / upgrade your transmission in-house.
