Rubrignitz

My GF hates everything I've done to the car. The dash and floorboard vibrate with the longtubes, solid driveshaft and off-road pipe. The harder engine mounts make the car vibrate and shake even more.. and now the 4.10's which just exascerbate everything else. It sounds and vibrates like a racecar now which makes her nervous. Personally I love it. ;-)

Don't mean to take this thread elsewhere, but how does the 4.10 ratio work with an automatic vehicle? I am considering a few mods ('05 GT) starting with CAI, the tune, then gear.
The car is driven 70% city and the 30% highway is usually a max of 85MPH.
I've been wrestling with the "3.73 may not be noticeable enough and 4.10 may be too much" thoughts.
I also must consider traction conditions in inclement weather and I know taller numerically gears have a greater leaverage effect to the rear wheels, hence more "breakin 'em loose" conditions. My concern is loss of traction (fish-tail) on take-offs, downshifts (of the transmission) on accelerations in these inclement weather conditions. I'd like to hear from those who made these gear changes and the "upsides" and "downsides" of their choice.
Thanks.
