how much of a diff do 4.10's make

i didn't get to test it out on this stang. on my last one i dropped 3 tenths in the 1/8th mile on the 1st run they are definately worth it

cant comment on track times, however it will make your car a whole lot more fun to drive.

7 tenths with them and a Diablosport. Definately worth it.

How difficult is it to get traction with them with an auto??

depends on your tires, track prep, tranny mods, etc...

Its the best mod for an auto. Hands down. Youll never look back. Traction isnt too bad, and its fine with some decent tires and warm weather. Made my car so much more fun, and so much quicker. I would hate to have less than 4.10s now!!!!

anywhere from 450-600 on average for the gears & install

where has everyone bought their gears from online!

i got mine from mustangtuning.com last week,i went with the motiv gears for 2 reasons ive been told they have less gear whine and they were on sale for $132 , i got a guy going to install them here hopefully next week for $60, looks like im getting a good deal

Mustangtuning.com here, Motives. Don't forget to use stangnet discount code.

Nice I wonder if the Motives are really up to par with the FRPP

i am goin to the shop today (saturday) and getting 4.10s installed on my 98 gt auto., along with rebuild kit, and speedo fixed.. quoted 565 for everying. 2nite i was kinda second guessing it, but after reading this post... thanks stangnet!

i went from 14.4 to 13.4 with dr's, 4:10, and practice in my 02 GT auto

Motives typically require much more shimming the the FFRP. This is also the first I have heard of people complaining about FFRP's having whine. Usually it is the other companies.

It's all in how you set up your rearend. If you take the time to do it right it won't whine.

I have FFRP is the back on mine and have no issues.

I installed Nitto drag radials after the 4.1 and the problem was solved. It cut my measured 0-60 mph time by 0.4 sec.

When reading how to pages on the web about installing gears they always talk about how anything other than FRPP gears will be a more difficult install due to having to set the pinion shim or something. You might want to use Google to investigate that. I am not sure of the exact details but I get the feeling FRPP gears are an easier install.

Also you will need magnetic base dial gauge and inch pound torque wrench to do install I believe...
