thinking of putting 4.11 diff gears in my xr8 auto. what are peoples experiances here with 4.11s?
What are your revs at 110kmh and how many K's do you get to a tank on the highway What colour speedo gear did you use when you got 4.11s Did they make much difference very interested in this mod and getting a hi stall |

honestly, if you do alot of highway driving and are concerned about fuel costs, this isn't a good option for you. I only have 3.9's but the gains are brilliant, it also seems to use less fuel around town, but it does use around 15-20% more on the highway.

4.11's are probly not suitable for highway driving, probly better off with 3.7's or something around there.

If you have a flash tuner, you can modify your tune to accomodate the diff gears. Wherever you gt it tuned will do it for free.
