Question about 4.10's okay i have a 2000 Z28 with the A4, i have a B&M shift kit,TCI 2400-2700 convertor, well what i was wondering is if i went with a 4.10 or 4.11 gear... what kinda rpm's will i expect out of lets say 70 mph in OD...i just wanna know what to expect for cruising purposes...to make my mind up between a 3.73...or a 4.10/4.11 gear...any help is appreciated thanks...
I have an M6 with 4.11s and in 6th gear at 70 Im cruising just a tad above 2k RPMs. I have definately noticed the drop in gas mileage on the highway above 70 even with the M6. Ive always heard of guys with A4s using no higher than 3.73 unless its a strip car.
