Could not agree more. I tested it back to back in my vette with first the wide ratio and 4.11' broke it on the first pass of a 2 day race, changed it out in the pits with the close ratio and lost 3/10ths and 3 mph. I have a real nice liberty built m21 fine spline with a steel mid plate and bushed case that I would love to trade for a wide ratio. When I rebuilt the wide ratio, I went with the m22 wide ratio and the maserio Italian gears. 3.73 gears and m21's are not first gear friendly. I am now running a 4.30, all I need at a stop light is 1st and 4th, 2 speeds are nice on the street.
