It seems like a very worthwhile modification for 6MT users.

Just remember highway fuel consumption is directly related to engine rpm. Not a 100% correlation but greater than 75%.
15% more rpms will decrease MPG by 11-12% especially as you exceed 60 mph [sweet spot for optimzation].
Whether a diff change is worth the $250-$400 in annual fuel cost is up to owner?

the 4.08's along with a cusco LSD are by far the best mods i've done yet...totally changes how the car feels. at 80mph, you will be at about 3500 RPM (which is where you would be if you were doing about 90mph).
just remember to take it to a place who knows what they are doing. they have to get the shims right to ensure that the ring and pinion engage properly, and they have to have the right equipment to be able to measure the correct preload on the thrust washer.

ummm at 80mph I am at 2900/3000rpm in 6th gear...are you sure..you may want to check that again.
imagine a 15% horsepower increase throughout the powerband...that's what it feels like (because the gears are 15% shorter). because the final drive is shorter, it affects all gears on the tranny.
