Question about rear end gearing on 2015 GT. Which is best?
So I just got my 2015 Race Red vert. automatic for the wife on Saturday. We love everything about the car and feel it is a step change better than my 2012 Boss in most ways. The only thing I don't like, besides exhaust being to quiet (already ordered exhaust) is it feels slow to get going. My boss seems so much quicker and I assuming it is gearing because the power is close to the same. My 2015 has the 3.15 vs. 3.73 in the Boss so I guess my question is... has anyone changed the gears in an IRS yet? Is it a much bigger deal than the straight axle? Does the auto transmission need to be re calibrated?
Which ratio should I get? I am thinking 3.55, but would love to hear from others.
