Just as title asks;
I am considering 410s but am curious as to the cruising speed at 75mph in 6th gear so I know what to expect from my fuel mileage.
Thanks

I know you said M6, I have an A4 with 4.10s and at 80 mph I'm at 2900-3000 rpm. I would think that you would be just a bit lower...

I am pretty sure mine was at 2100-2200 rpms. It was at 2000 at 70mph.

Mine pulls 2,000 rpm at 70 with 4.30's and 28 inch tires. Don't worry about 4.10's being too much gear. They are great with the 6 speed. It actually optimizes your power and mpg a little better at cruise speed.

I think I'm around 2k too. IMO M6 cars should have come from GM with 4.10 gears. The mileage wasnt hurt bad enough to even complain about and the butt-o-meter is reason enough to justify the mod.

I really need to get some 4.10s beceause with 3.73s in 6th I'm at 1500-1700 which is real sluggish on my car so I just keep it in 5th. Only problem is, I'm debating whether or not to put money towards new gears only to launch it at the track and get the noises.

Put away the $400 or so you would spend on gears and sit on it until you've got another $2k to drop on a rear end. I've been down that road before and I spent 4 years going back and forth. Finally I dropped the cash on an S60 and I couldn't be happier.

Slightly off track, but not much, I'm running 4.30:1 rear gears and have exactly 1950 rpm at 70mph... close to what your asking

~2K RPM at 75 MPH, actually makes the car more driveable on the highway and not as sluggish in 6th.
