So I have a automatic thinking about getting 4.10's. So how bad will this f*** up my gas milage because I drive highway? And is there anybolt on's I could get to try and aleviate it if it's too bad? Or would 3.90's or 3.73's be the better way to go.

 

The reason is I got offered a new set of gears of my choice for $100

 

just do it and forget about it. then when you go to the 1/4 mile track you can say i went 13.4 13.3. i would of got em but i had future plans of getting boosted.

everybody drives on the highway. i have a 30 mile a day roundtrip to work and home. i fill up once a week. it wont affect mpg all that much. i went through the same thing you are going through just get the 410's and call it a day.

 

No seriously is the mpg on the highway way worse.....

 

No its not, the hard part is from keeping the gas pedal floored the whole way..get 4.10's u will love them!

 

i put gas in my car when it hits the low fuel light and my miles will read somewhere between 240-260 depending on my driving habits. since you do a lot of highway driving you should do a little bit better then my car with 410 gears.

 

Just get the 4.10s and be done with it. My mileage went up actually, because I can keep it in 5th gear now.
