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.

 

motive 390s with 2 quarts of gear fluid. i used the install kit at 40k and i was fine so its up to you with what you want. a lot of people say get bearing kit for cheap insurance.

 

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.

 

I've used motive and FRP and they're both great.

 

hey.. all I do is highway driving and I have 4.10 gears and cams..

it's not the highway driving that gets you.. its the stop and go traffic.

 

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.

 

I can't believe I forgot about this video.
Keep in mind I am NOT trying to change your mind. Just trying to give you some good FACTS!

i would get the frpp gears and master rebuild kit. if you have extra money i would go 31 spline. i got everything shipped from steve on svtperformance for around 500 bucks(frpp gears, cobra trac-lok, axles,girdle, master rebuild kit)

Off Topic, I know, and apologize for, but I just had to say;

MCMMOTORSPORTS: That's one bad-*** sig pic.

 

Why thank you. I didn't make it though.

 

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.

 

go there, it will tell u everything you need to know

 

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 *** after awhile. Not to mention in the knee for those of us that have had knee surgery before.

 

Had 3:73's and can't believe how much better the 4:10's are!!!!!!!!!!!!!!

 

Also I think I get better gas mileage on the highway now than with the 3:73's.In town I'm not sure,can't keep my foot out of it long enough to be able to tell!!

 

Ok well sounds good i'm down to 3.90's or 4.10's. How bout you MattJ? Why did you go with 3.90's over 4.10's?

 

Just get the 4.10s, I've never had 3.90 but would imagine they are pretty close to 4.10 with only a .2 change in ratio. I considered 3.90 but knew I'd regret not going all the way with 4.10's. I haven't noticed any change in gas consumption but the car is only driven 1-2 times per week. I don't notice any significant increase in rpm until about 45-50 mph.

 

I went with 3.90s because the possibility of forced induction down the road. I want to keep my options open but get the most out of what I had. All I seen was the argue between 3.73s and 4.10s, so I went with 3.90s. I still see these retards argue over 3.73s and 4.10s. half of them dont realize theres a middle line there with 3.90s.

besides who else has 3.90s here? Mabye a couple people?

 

btw the difference between 3.90s and 4.10s is very minimal. you may pick up a solid .1 in the 1/4 if you are lucky.

 

I went with 4.10s and have no regrets. I'm probably the only dumbass to wait until gas prices went up and then install 4.10s + a 93 octane tune.

But it's worth it everytime I step on the gas

 

Nope your not the only one :stupid:

 

reason i went with 3:73 is i like to take my car on road trips from time to time and i dont want to do 3000rpm down the interstate

 

Welp......I WAS also one of those people that couldnt figure out what gear I should get....3.73....3.90...or 4.10.

the 3.90's were pretty much outa the question just because I preferred the FORD racing Brand..and heard to many people complain about gear whine and install frustrasion with them...so those were ruled out quikly.

so..i was stuck between 3.73 and 4.10. I was going more towards the 3.73 gear cause i was scared that the "ride quality" of the 4.10's would be tooo steep for me.

let me just say that I have a couple friends I just met with stangs..both being 2003 GT's. One with 3.73 and one with 4.10...both with the basic bolt-ons. but the one with the 3.73's is getting a Kenne Bell 1.7 sukking hoe installed soon. I drove BOTH cars around the block cause I wanted to feel the difference MYSELF. let me say...4.10's it is!!!!! They feel like I can take out any car from the line and or rolling.

Imma get me some 4.10's. u can barely notice a difference with 3.73 and 3.27....trust me.

 

+1 3.73's just don't give enough bang for the buck, but don't let people fool you 4.10's do affect gas mileage just not that much, and the increase in acceleration will justify the loss of about 2mpg.
