Hey 17 mpg on the highway sounds like a ******* blasty blast to me.....

Do what you want dude, its your gas money. I'd rather put that money into a good converter if I was you.

4.10s is perfect for an M6 car. You'll still be turning sane RPMs on the freeway, too. I think I turn around 2400rpms at ~80mph IIRC with my 4.10s.

4:10/11 with a girdle will hold pretty good until you put stickies on and try to dead hook it.

I personally, wouldn't pay for the 3.42 to 3.73 swap. I don't really know how big of a difference it would be. My car had the 3.73's in it, when I bought it. I wish it had a little more get-up and go. I plan on changing them to 4.10's when I get some more money built up and a few other things done first.

Put in your info and it'll tell you how many RPM you'll be running at what speed.
