| Should get you into the 14s, but you highway MPG's will go to shit. Talk to crovo, I think he's got a set of 410s he wants to sell.. | |

Yup with 4.10s and True Trak I had a best of 16MPG highway, but that car launched from the stop light, loved it, well worth it. Never ran it down the track though. Doug | |

I had the True Trak and it hooks like a mother, you should not be able to spin the tires more than a chirp...that's the point of an LSD... Doug | |

| Yeah, 4.10's are FUN in a 4L60 car! Make sure you have a good set of rear tires or you will have BIG traction problems on the street. I loved that. I do have a set of 4.10's that I am not using, but I think they are already spoken for. If not, I will let you know. And I got between 15-17 mixed MPG with the 4L60/4.10's/26.5" tall tire. I only lost about 1.5mpg or so. WELL WORTH IT! | |

| I had 4.11s in the Roady, they were pretty fun at first. After a while I got annoyed at the RPMs around 55-60 MPH. I also felt that the first gear was way too short with the 4L60E. I barely had enough time to feel the pull of first gear, then it's the horrid 2nd gear drop that we all experience with the 4L60Es (Unless you buy a $1000 planetary) Doing it again I would not go over the tried and true 3.73s. Gas mileage was around 17 MPG, not bad enough to annoy me at the pump thankfully. But if you're excited to get them installed, then more power to you. | |
