when u changed ur gears wat else did u change onit
|
31 spline axles, frpp t lock, frpp girdle, welded axle tubes/torque boxes, MM lower control arms, Steeda sport springs, bilstein shocks/sturts, MM c/c plates, steeda ball joints/bumpsteer kit. I had all the suspension and rearend done at the same time. Not sure if you're asking everything that I did at that time, or what else needs to be done when changing gears?

When I got 4.10's installed I got the ford racing 4.10 ring/pinion gears, install kit that comes with shims, spacers, pinion seal etc. I also got new axle bearings (car had 55k miles at the time), rear end fluid and friction modifier. Have your clutch packs inspected as this would be a good time too have them replaced if they are worn from abuse/miles
|
Thanks, SLP.
My '05 GT is an automatic, has 14,800 miles and is a city driver. I drive highways every once in a while. Could the gears cause problems for me in the future? If so, I won't change gears at all. Just to have a little more 'oomph' isn't worth having significant problems in the future. |
Your car will be fine with the gears.

A friend of mine just installed a set in his 07 and said he would help me do mine, said it wasnt bad just unbolting everything from factory was the hardest part. |

the only complaint I have with my 4.10s is there is no "happy" spot with the rpms at 45mph which is the speed I travel around here 90% of the time. 4th gear revs a little high for my taste at 45mph and 5 gear bogs the car at like 1300 rpms.

and quit making fun of my skinny tires..... :p |

How much did that all cost you, I have entertained the idea recently...but I drive the highway most of the time with 100mi. trips daily to and from work.

Gears are the best mod you can do to these cars. All you need to do is refine your driving style a little. Like the rpms at 45, they will be higher than before but wont hunt anything, actually this will help in city driving because the motor will be closer to the power band and you want be on and off the throttle all the time. Just give it a couple days and youll love um.

I paid $723 for all the parts and speed cal to recalibrate the speedo and labor and was well worth every penny. As for the highway driving it should be fine I think im turning 2000rpm at 65 miles per hour

I may sell my 4.10 differential as I bought a new differential and will likely go with 4.30's. The 4.10's are like 2.87's in OD and 4.30's would be like 3.01's, a 4.7% difference or 2617rpm at 65mph, hardly a difference. Gears can be gotten for $149. and the install cost me $200. plus the install kit, about $109.

everybody is talking about the city driving, how about the highway driving difference? to the mpg ?

I have 4:10's and i average 20-21mpg in both city and highway
my car's epa rating is 16/21 just dont drive like an asshole and keep yer rpms under 3,000 and yer fine for highway driving. 4:10's destroying gas mileage is a myth for a stock mustang gt. They just arent steep enough. I usually cruise 75mph on the highways, and still get over 20mpg |

I just dont know about that I've had my 00 since day one and have never made over 20mpg, my best was just under 19mpg trying extremely hard.
i also have some intake work , exhaust, and a chip which helps a bit, and it is an auto. |

Whoever says that 4.10's are too much gear for the street, is wrong. I though 1st gear would go by so fast and would be practically useless, but it's not. 1st gear is not that short at all. The biggest difference I noticed was that 2nd gear goes alot faster. It does pull a bit harder, but i thought that it would really put me in my seat. 1st gear and about 1/2 of 2nd spins, but the car still moves. It does not fry the tires in place. I would've been so disappointed if I went with 3.73's.

Congrats, the more you drive it the better it will get and all that other stuff will only help help the Butt-o-Meter. I think once you hammer it one good time, youll be hooked. :D
