[Mustang @ heart]

I was thinking about improving my mustang's quickness with a CAI and custom tune and I was wondering how much 3.73 gears would help, and more importantly what other mods I will need to keep my drive train safe as it is my daily driver. Thanks in advance!

dont do 3.73's
right now you have 3.31's so u might notice a little difference but not too much.
go 4.10's and an LSD, trust me its way worth it! i have 4.10's in my daily driver and its no big deal at all!
i still average about 21 mpg and it is a helluva lot more fun to drive than stock, even my dads old friends who are muscle car guys say, "damn, this thing feels and pulls like its got a V8 in it!"
trust me dude, you will like the 4.10s way more
