Default Alright Time for gears!!!

Ok so i went to the track tonight although the track was prepped badly and all and it was hot i still ran very badly. I'm sick of it so i'm gonna get gears this summer. I'm prolly gonna get 3:73 or 3:90 but i wanna use FRPP gears i will likely go with the 3:73's. My question is with 22,000 miles on my car do i need to buy the master bearing kit or should i just purchase the installation kit? Also what do i need to do to get my Xcal 2 reflashed for the gear change? Also should i buy three quarts of the royal purple gear oil? These are my questions. I've made up my mind to not go with 4:10's so don't ry an change my mind i do to much highway driving. It's either likely gonna be FRPP 3:73's or MAYBE Motive 3:90's but i think i'm gonna go with FRPP. I'm tired of embarrasing myself at the track dammit.

I heard that motive performance gears were not great quality though. I've always heard FRPP makes the best gears for stangs. So i need two quarts gear oil not three? Once again how do i get my tune changed on my Xcal. 2? Do i mail it back to MT or do they email me a tune or what?

you can edit the tune yourself when loading your tune. yopu just goto custom user adjustments and itll be in there. I have motive 3.90s in mine and they work absolutely fine with zero problems.

Almost 2 years with Motive 4.10's in my 04 GT with NO PROBLEMS and I have been S/C'd for 10,000 miles too. Nothing wrong with Motive gears AT ALL.
Soon you will realize that not everything you read on teh intraweb is the truth.

He already said he made up his mind NOT to go with 4.10's. That is why I said nothing about how great the 4.10's are, even on the highway.

lol.. I almost went with 3.73's and I'm 239846792347x glad I didn't, it was worth trying lol.

but yeah.. you wont need the bearing kit, and probably not the install kit if you end up using FRPP. Im not sure what all the motive gears comes with.

Ok maybe i decided prematurely on my gear ratio. I do quite a bit of highway driving, but i also do tons of stop and go driving from streetlights so...... I wanna get a good bang for my buck but i cannot afford to lose gas mileage or else my parents will eat my car! So once again i'm now leanin towards 3.90's. Tell me pros and cons of 4.10's please. Also maybe pro's and cons of 3.73 and 3.90 gears. Thanks for the video by the way.

Ok so i kust read everyhting in the Official Gear Thread and my questions are not answered. Once again what are the cons of 4.10's, 3.90's, and 3.73's and if you have one of those ratios in your car tell me why you chose that ratio over the others. I do an equal amount of highway and stop and go traffic daily so i need a reasonable gear ratio that won't hurt my gas mileage to badly. Thanks

I will be brutally honest here. If you are that concerned over gas mileage, you need a 4 cyl daily driver. Stop and go driving with WHATEVER ratio is going to kill you MPG's. Only with hwy driving at a constant RPM will you see GOOD mileage out of a Mustang. Gears won't really help that. If your choices are between 3.90's and 4.10's, do the 4.10's. It is NOT that much of a difference MPG wise. I get between 17-19 MPG stop and go around town. I can squeeze out 21-22 if I shift before 2,000 RPM's and keep it under 55. I know with the sudden increase in fuel costs, it is making fuel mileage a bigger concern for many people. I just learn to live with it because it is something I have no control over. Now, if it was creating a hardship trying to get around town, I would buy me a scooter and be done with it. Either way, keep searching for 5 spd people that HAVE 4.10's and see how many of them love 'em. Again, I said look for people that HAVE them, not people that think they know about them. One last point, N/A my car ran a 13.65 in the 1/4 with the 4.10's just hitting redline as I crossed the line in 4th gear. That was with a crappy 2.05 60 ft. No times yet with my S/C cause I need some slicks or D/R's.
Good luck with whatever you decide.

I'm not by any means a "do it yourselfer" when it comes to cars, as I just don't have the knowledge base (yet :clap: ) so this info is basically just a relaying of stuff I found out/was told when I was looking into 4.10's.

The main thing that was mentioned over and over, and this was usually a con when measured against daily-driving, was that you essentially took 1st gear out of the driving equation because you had to shift so fast into 2nd, and even 2nd wasn't that forgiving in the "up-shift NOW!" department, so if you lingered to long in those gears you would be reving high all the time, thereby burning up a bunch of gas.

The other thing was the constant up-shifting/down-shifting if you were in a bumper-to-bumper type traffic situation. That gets to be a pain in the ass after awhile. Not to mention in the knee for those of us that have had knee surgery before.
