Fox body Mustang owners used to swap out the ring and pinion to 3.55 or 3.73, for better performance. My 2011 GT came with only 3.31 option. However, first and second gear are very low. All of the 1st Gen A4WD came with the 'tow' package. A hitch receiver, transmission cooler, bigger radiator and 3.73. $1500/48 months is $31/month more.
