The mods in my car : No Cats, Iridium sparks, CAI BBK, TB 75 mm BBK and Sniper Programer.

I want to install new gears, but im not sure which one.

my car is automatic... which is the best 3.73 , 3.90 or 4.10

i like the 4.10 but how much MPG can i have whit this gear ?

and sorry my english sucks jajaja

hola..... mi espanol es mal..... n e ways welcome to the forums. nice lookin ride. that gear question will spark tons of controversy so just beware of whats comin. most ppl will say 4.10s. thats what id say if u drive in town a lot and not a lot of highway driving

Welcome to the forums! With an automatic, 4.10 gears are the way to go, since they make up for the loss of power inherent with our transmissions. If you plan on doing F/I in the future though, go with 3.73. Your MPG shouldn't be affected much, probably 1 or 2 MPG depending on how you drive. Like everyone says on this forum, your right foot affects your MPG the most.

thanks
for quick answers
tomorrow i will take the car to install the gears
4.10

how much can improve in 1/4 mile.

my time is 14.80 in the track

I've read that you can shave 0.5 seconds off your track time with gears. Maybe more if you push it hard.
