about 4:10's
 

I was talking to my friend... older guy like 45-50, and he said that if you put 4:10's on my mustang the braking will go to hell and you will probably beak your back end (IDK if he meant by braking too fast or what) ... he said AT THE MOST go 3.73's... any input from people that have 4:10's

RE: about 4:10's
 

Don't know what that guy is talking about but my 4.10s change nothing except for my acceleration. Its alot more pick up down low, though my top end suffered a bit. I would go 4.10s and I speak from experience.

4:10's it is then :D

RE: about 4:10's
 

thats cause back in the day when he was young they had differnt gear ratios, so 4.10s would be like 5.12s now a days, at 80mph you will be around 3k rpm, might even want to think aboot 4.30s;)

RE: about 4:10's
 

speaking of different gears,how much does the car suffer up top with 4.10's i want more acceleration but i dont want the top speed or the high end torque to suffer it already doesnt have that much power the faster i go in 4th so do they have a gear that is made for both top end and low end torque.

my car pulls hard even up top, unless your going 150 mph 4.10's arnt going to hurt your top end, this is another 4.10 myth along with gas mileage the one:D

RE: about 4:10's
 

The old dude has no clue. Back in the day cars did not have overdrive trannys, so yes with a 4 speed a 4.10 was a pretty steep gear if you wanted to drive on the highway very much. With a modern car there is no reason to not go with a 4.10.

+1 on everything everyone else said. Now onto the breakage issue. Don't worry about it unless you are driving a huge torgue monstor with alot of grip such as FI and slicks of some kind. That's where you might start to have those type of breakage issues. Below 350-400 RWHP you will be alright as long as you aren't brutal to your car.

RE: about 4:10's
 

It works like this. You will rev higher at the same speeds, which means you will run out of 4th gear earlier then you did before. I run out at about 120.. used to push 150 on a flat long straight away in 4th when I did the "How fast will this thing REALLY go?" thing we all do.... But your top end will stay about the same really.. WIth steeper gears you can accelerate at any speed in 5th. For example, I dont have to downshift to fly by people on the highway to and from work from 5th gear. You will not reach the top speed of your car as quickly anymore.. but you can still get there. And Gas mileage stays about the same.. just flop highway and city around and there ya go.

i just got mine in last week, they are the right gear for the car. but i wish i had a 6 spd :(

RE: about 4:10's
 

It boggles my mind how much people think that 4:10's are way too much of a gear for our cars. It gets annoying. Get the 4:10's.

RE: about 4:10's
 

i asked some one about the 4:10's for my car and they said my car couldnt handle it,im not a mechanic ,so i really dont know to much about cars but am learning quite a abit

RE: about 4:10's
 

here is a great general rule about gears. IF YOU ARE TALKING TO SOMEONE WHO DOESNT HAVE THE GEARS, YOU MIGHT AS WELL GO ASK YOUR DOG! thank you.
