I have only worked with 486 rears. I was wandering if anyone would put there input on there preference. Or if they even think there is a difference; on the track, in performance or feel.

Depending on where you run, the 4.11 is what is needed to achieve the proper gear set without having to turn the gears upside down. The 4:86 is used on the shorter tracks to achieve a more 1 to 1 gear ratio decreasing the gear split and decreasing horsepower loss through the drivetrain.

Either work fine with the 4:11 a little more versitile, but I would be surprised to hear someone say they could "feel" a big difference between the two. Maybe I'm wrong about it.

1/2 miles wing car more so on a 4:86 ratio look at a gear chart nothing between 4:86 and 5:04

4:11 ratio there is

another deal is well there is prob a lot of good reading out there on the subject

prob is everything changes so much

every year these car just keep getting faster lighter more horse power better torque better engines and tires younger dumber drivers
