Apologies for any ignorance, but this is a new area to me, so I need a bit of help.
Originally, when I bought my V6, I didn't pick the 3.55 Gear Ratio option, so I have the 3.15 right now.
Recently, I stumbled across this: http://www.americanmuscle.com/frpp-355-gears-2015.html
So I have a few questions:
1. How much of a practical difference is switching to the 3.55 compared to 3.15?
2. How easy is the installation? Is it easy to undo the installation if needed (car is leased, with 80% chance of buyout at the end, but I want to be on the safe side).
3. How badly does 3.55 affect fuel economy for a daily driver?
4. For a daily driver, am I correct in not switching to 3.73 to keep things balanced? Especially during winter, I don't want to have a risk of losing traction every time I launch.
5. I have an automatic transmission. Would this cause issues besides having to adjust the shift points?
6. Does this mean my car would need a tune after installation? This article (http://www.americanmuscle.com/mustang-rear-differential-gears.html) says it may, especially for automatic.
7. How can I guarantee the adjustments to the transmission are safe, and what do I need to watch out for from the installer?
Thanks in advance!
