ArkansasHog said it all- I highly recommend 4.10's. I have no issues on the highway, 3,000 RPMs at 90 MPH.

Not a thread hijack but what you guys make of this?
My FR 4.10s are run in. Nice dry day. Took the car out for a WOT run and hard launch. I`m not the hard launch kinda dude but I thought I`d try it anyway as I`d never tried it.
Car is a 2003 GT Auto. Diablo 93 tune, Accufab plenum TB, K&N, catback etc. You get the picture. BEFORE the 4.10s went , on stock 17s and 3.27s the car could spin a tyre, no problem and chirp 1st/2nd easily.
Now after the gears I`ve added 18s with Michelin Pilots 295/35/18s.
Same launch. OD off and Traction control off. No spinning. 1st gear felt longer than I thought it would. Into 2nd there was a bit of slip then on to 3rd. Absolutely fuss free. I wasn`t expecting that.
Whats the deal? Was I expecting too much from the gears? It either feels like I`m down on power or I have plenty traction. I mean the car certainly tramps to 3 figures in no time and it drives fine so it can`t be power thing surely. It just doesn`t feel as `frantic` as I thought. I watched a couple of 4.10 videos on youtube and they seemed more `fun`.
I`m actually thinking now I can go down the blower route even with the 4.10s. Any thoughts gear heads?
You can add gears and they keep you in a nice powerband perfect for a 1/4 mile type environment but gears don't add hp; they help a good driver stay in the right place in the powerband and with practice could potentially help the ET in the 1/4 mile.
I think it's because of the automatic. The auto tranny doesn't allow quite as big of a 'shock' to the tires, and that helps retain better traction. Plus, our 1st gear is 2.84:1 while the 5 speed guys' 1st gear is 3.38:1
That being said, I know exactly what you mean. I hear this talk all the time of mostly stock Mustangs laying down rubber 1st and 2nd gear; all the while I'm making 330 ft-lbs of torque at 2000 rpm with a positive displacement blower
No, 90 MPH and my speedo is calibrated. Should be 2,661 at 80 MPH, but whatever. Speed limit by me is 55 and I usually don't exceed 70 in the Stang. Type of exhaust definitely factors into highway drivability.More like 3k rpm's at 80 mph.... and that sucks for on the highway

Now I'm curious... what kind of MPGs are y'all pulling in with 4:10s around town? Highway? Or do you guys even care about getting somewhat decent mileage in your Mustangs? (mainly a question for those of you who also DD your Mustang)
Not trying to flame anyone, but an honest question since this thread is on that topic already. I have 3:55s sitting in a box in my garage but am not sure I'm wanting to have to pay more at the pump just for more seat-of-the-pants feel since I'm on the highway a decent amount and I do like getting over 25mpg.
