Do you have 4.30s, if so GET IN HERE!
I'm just wondering if you daily drive your car. What RPMs are you do you turn @ 70 MPH. How much have they affected MPG. I don't plan on adding any type of forced induction anytime soon so I wanted to see peoples experiences I'm torn between these and 4.10s

i've got 4.30's in mystockish GT and i love them. it is my daily driver and i drive about 75/25 highway/local. cruising at about 75 is right at 3000 rpm, pretty high. they suck on the highway gas wise and are more efficient around town............if you keep your foot out of it which I DON'T lol. they are great gears, if you're btwn 4.10 and 4.30 just get 4.30 and never look back!

Running 4.30s on an 04 with stock internals. If you dont mind running high RPMs and not using 1st gear much, they work pretty well. I noticed alot of difference when running in 3rd and 4th on the high way. (no need to downshift to pass!!!)
