best diff for highway cruising

[///M42 sport]

is 2.93 a good one for optimal mileage?

I wanna hear some real life experiences. Thank.s

[e30_3I8I]

I personally never experienced the 2.93, but ive heard its good on gas on the highway because its such a tall gear.

[mr.vang]

i would like to know also.. did the other thread got you interest about it? lol

There's also a 2.79lsd fyi....325e's had them...

a 2.93 will put you at about 2500rpm for highway speeds (~70). if you don't care about anything but highway mileage, get the tallest gear you can, probably a 2.79 or 2.93. simple

[caliGreen]

yup indeed m20b25+2.93= 2500rpm on highways. i call it the "6th Gear"

[Kershaw]

yep. i never feel like i need another gear in my eta. 2500rpm seems to put me at the flow of traffic. ~75mph.

2.93.

i average 28mpg.

I had the 2.93 still when I did the 885 top end swap, and it wasn't that bad on the streets, second gear was awesome. Went to a 4.10 and am hating it, basically feels like I just moved all the gears down one and have 1/2 of a first now. When it was still an eta, yeah a gear would have helped it, but if you have an "i", 2.93 is awesome for highway driving! I could go as low as 30 and still pull a little in 3rd, but also could pass at 100mph by downshifting to 3rd lol.

come pick up my 2.79 in PA. 100 bucks. haha.

really? 100 bucks sounds very inviting

I can assure you a G260 + 4.27 is not the best diff for highway cruising. Unless you like never having to shift from 20mph to 123mph.

Now a TR6060 and a 4.27...

Yeah dude. What anymore feedback on mpg on a stock 325i and 2.93 lsd?

Sorry can't say stock 2.5i, but the eta/2.93 was 22 city 27hywy, 2.7i/2.93 was 20 city 24 hywy, let's forget about the 4.10 plz thx.

[Dude]

3.73 in an eta works good =P
