Last year we installed the Airaid CAI on my buddy Shawn's car. This year he did a few more upgrades. The dealer did mods 1-4 earlier in the week and we did mods 5-7 this afternoon. He just ordered a BamaChips tune for it.
I got to drive the car today and I have to say the 4.10's feel sweet!! Real inprovement in overall drivability of the car. I had it on the highway and at 100 KM(63 mph) it was only turning at 2200 rpm. It used to feel quite sluggish before the mods but the gears and other goodies really woke it up. It now jumps off the line and goes!! The GTA's sound very nice, nice and mellow when cruising with no drone at any rpm and a very powerfull roar when you stomp on it. I can't wait to bolt on the drag radials and take it to the track.

I have six dead bolt locks on my front door. when i leave the house i lock every other one, that way no matter how much someone picks them, they are always locking three.
Yeah we got it done pretty quick. It took less that half the time to do his spoiler as it took me to do mine and I made Shawn use the Goo Off to clean the tape and sticky stuff left by the stock spoiler. It also only took about 15 minutes to do the sequentials. I really like the redfire too.
i love my shade of red fire ( only in 05 aparently ) in 06+ it gets a hair darker.
word is mines "ultralight redfire"
its light. its flaked, its hot!
when ford painted my hood scoop they screwed it up and got it to dark useing the paint codes, that were updated in 2006

Looks good. What does the 4.10 do? How much does it cost? How long to install?
The 4.10:1 is the gear ratio in the differential (rear end). The stock gear ratio in his 2007 automatic transmission car was 3.31:1. Going to a higher numerical gear in effect gives you more leverage when you accelerate off the start. The price for install varies, his were done at a local Ford dealer up here in Canada. Typical prices for installs range from $500-1000 installed and can usually be done in less than a day.
The Gear Ratio
The gear ratio is simply the number
of revolutions that the drive line has to make for the tires to make one complete revolution. One revolution of the rear wheels usually moves a 1965 to 1973 Mustang a little over 6 feet.
If you have a 2:80 to 1 rear end in your car. This means that the drive line must make 2 complete revolution plus 80% of another revolution to turn the rear tires one complete revolution. So with that in mind, it's easy to see that the drive line in a car equipped with a 3:50 rear end would have to make 3 complete revolutions plus .50 (or 1/2) of another, and that the drive line in a car equipped with a 4:11 rear end would have to make 4 complete revolutions plus .11 of another, and so on.
It is important to remember this fact. If you change from a 2:80 rear end to a 4:11 rear end, the car will go slower at the same engine speed. Since your speedometer is operated by your transmission and will be calibrated for the 2:80 rear end, it will tell you that you are going around 90 miles per hour when you are really only going 60! Remember that you will need to have your speedometer adjusted whenever you change gear ratios.
Also, the 2:80 equipped car will have a much higher top speed than the 4:11 car but it will take a lot longer to get there. How this effects most of us in our street cars is that we want a happy medium where we have good low
end acceleration but the car is still comfortable going down the freeway at 60 to 70 mph.
Yup, no thanks to me for pushing him along. Oh another thing I noticed was that his car had no noticeable wheel hop. I even did a burn out and left a 20 ft pair of tire patches and no hop!! Yeah!!

Yeah stock arms!!! I did a good burnout and 3 launches with it loaded against the torque converter at various rpm's and on the launches with wheel spin there was no detectable hop. We'll see what happens at the track with the drag radials and a VHT prepped track. I gotta say I highly recommend 4.10 gears to anyone with an automatic equipt car. They work fantastic and are even good on the highway.

I've heard of that happening. Don't have a good explanation why though.
I managed to get one full run in on the G-Timer. With both of us in the car (we both weigh about 185 lbs) it ran a 14.33 at 97.8 mph with a wierd slow shift into third and a weak 2.1 sec 60 footer(spun the wheels a bit). The DA was fairly high, over 4100. the corrected time is 13.594 at 103.147 mph. Right where I was expecting it to be. DA Calculator - Density Altitude Calculator - DragTimes.com
Redfire 2007 mods installed with pictures. 
He just ordered a BamaChips tune for it.
looks like alot of fun
