Yes this helps a TON on an auto car.
3.42 gears instead of 3.08s and a Limited slip differential for better traction.
I beleive a M5 still has 3.23s, but with the LSD.Comment

My car is an auto i am looking dreound for a good shift kit not just the improver. Does anyone know of any good ones?Comment

transgo shift kit is a great kit that many people have here. If you go that route make sure to get a vette servo at the same time for some nice firm shifts.Comment

do a search and you will get a ton of info on the kit and servo as well. It is at the top of the page under the buttons. All the info you will need is right there.Comment
