Немного грустного о коробке...
What about 06+ WRX owners? Your final drive is 3.70 vs the previous year models' 3.90. This in effect adds 6% more load to your gears vs. previous years. While it's impossible to calculate this into the shock load formula mentioned above, it is noted that there are an increasing amount of 06+ owners with broken gears being seen here. So shift/drive kindly, investigate increasing your apparent final drive through smaller diameter tires, and temper your power modifications based on how soon you can afford to upgrade gears.....
