Re: rear end ratio
I'd live to change out the gearing on the rear end of my xf. I have a six-speed and find the 1st gear almost entirely useless. Its a real granny gear, almost like that of a pickup I used to drive. I usually start in 2nd because 1st is so low. Another added bonus, better mileage! Using sixth as a true overdrive instead of a displaced 5th, and the xf could get in the mid to high 30's on the highway. The engine has plenty of guts to do it as well. Fore some reason, every manual I have driven lately has been screwy with a six speed. Kind of like they just threw another gear in for the fun of it, and not for any specific function.
