If you're staying NA on the stock getrag but want more pickup I would say 3.73 is a good ratio without making the lower gears totally useless. If you're going FI then you actually want a much taller diff to stay in boost for a long time, like a 3.15. __________________ ![](image.php?s=b1d8e9555dac6a39f0db2ce40cda6abb&u=9846&type=sigpic&dateline=1373440016) -Alex |
