I used to really want one of those transmissions on my BRZ until I heard one in real life.
They are incredibly loud. I wouldn't want to be cruising down the highway at 70 mph with one of them.
I did hear that you can get transmissions that use straight-cut gears for the first 4 gears and then normal gears for the top 2, but eh...not worth how much it would cost just because I like the sound.
That's still going to need to have bearings supporting the shafts that are able to support thrust loading (when power is applied in either direction in one of the helical cut gearsets).
