Chris,
At what power level do you see guys looking for this 2.32 gear ? How about straight cut version ?

The ratio is good for anything over 600 hp with small tire or narrow power band .Straight cut is not an option at the moment although someone suggested making the rear out of straight cut if the washers in the rear gear set get abused.I like it in street 4L80E too.
