FRPP 3:73's are great. I love mine. First, 3:55 not worth it may as well be stock. second, 4:10 a little much for me I do a lot of highway driving. 3:73 perfect. I did run a 13.6 with them and still cruise around 2 grand in 5th on the HWY

Get the 3.73 or 3.90 for all that highway driving 93 octane is expensive right now and only getting higher.
you should be running 87 octane anyway. it's what the GT was designed to run on. check your owners manual right there on the very last page "Filling Station Informationrequired fuel - - - Unleaded fuel only - 87 Octane."

unless your timing is advanced.

3.73s will pull roughly 14% harder than stock, 3.90s pull roughly 19% harder, 4.10s pull roughly 25% harder

^^^^ If someone would put this on a sticky along with the info on what rpm's you are at at normal speeds (30,45,55,65,75) for both the 5 speed and a auto trans, that way when someone want to know what gear they should get we can direct them to all the info they need!!!

you actually think that would work? every day there's like 3 or 4 active gear threads on page 1 that all ask the same question and have the same answers.
