Pros and Cons of 4.10's

[jmk97GT]

But dont most stang owners "plan" on being S/Cd? I am getting TTs, so 3.73 WITHOUT a doubt...heck I may need 3.55s so i can stay in 4th gear through the traps, especially once I forge the engine. Thats what you guys should look at...dont plan on trapping much over a 100 and are just going for some boltons, 4.10s ALL the way. Putting head/cam combo in and staying N/A....mild cams only I say go with 4.10s anyways due to increased RPM range....HOT cams/head setup, 3.90s are your gear IMO. Any nitrous/super charged/turbod cars, go 3.73s as you will be trapping 111+, and unless you have a built bottom, 4th with 4.10s WILL NOT get you there with your engine still intact.But hey you can do whatever you want, thats JMO.

Thats why I am so unsure weather to even get gears at this point. I am debating weather I want this car to just be a bolt on until I can save enough money to get something faster, or if I want this to be a sleeper. Right now, its slow as hell with 2.73s. I wonder how much improvement I'd see with just 3.55s

I got 4.10s in my daily driver and have no issues with them. I didn't notice much fuel economy change at all. I think the higher highway RPM is offset by the more efficient stop and go? Of coarse I have never had 3.73s installed to compare it to.

When I can afford a KB, I'll be able to switch rear gears at the same time. Til then it should be 4.10s or more.

I had 3.55's and went to 4.10's. With the 3.55's on the strip I could hold through 3rd or shift to 4th going across the line. Now with the 4.10's I have to shift to 4th.

I gained about 2 tenths iat the track with the change and gained lots on the overall driving or the car. Fun factor before 4.10 "7" Fun factor after 4.10 "10" for sure.

One thing to remember is that any gear over a 3.73 pretty well blows the stock tires off up to third. So if you have traction issues now get that under control before the gear swap.

when i am going 50-60 i drop down to 2nd and haul ass. i still get like 25mpg on the highway but around town since i cant seem to keep my foot out of it i get like 15.

My god, I don't come even close to getting such good gas mileage in my car, with stock gears! I do a good 50/50 highway/city driving, and I get 18mpg on a good tank!
