With a 6-speed, you really don't have daily drivability issues with the 411 setup because there are two overdrive gears (5th is .75, 6th is .5). By the time everything gets multiplied out, your cruise RPM doesn't go up that much.SPANISHVETTS said:I am a bit late popping in on this but here is my $.02 worth anyway. I have never seen a set of quiet 4:11s after they have a few thousand miles on them. Even the ones from the factory start to whine while they are still ¨new¨.
The 2nd thought about 4:11s is the daily drivability; it is almost as uncomfortable as driving around town with a 3000RPM TC. Of course if your daily driving is on the strip with an 8000RPM engine and close ratio 4 speed the 4:11s are the way to go.
