The testing write up says that Ford rears may benefit more from this process due to the position of the pinion, which causes Ford rears to be less efficient than GM and Chrysler rears. Maybe we can find more info on the 05 GT that got 7-9 rwhp gain from JDM engineering.
thats right. a friend of mine stayed with a gm 12 bolt in his camaro for that reason. it is not as strong as a ford 9 inch but it does not suffer from as much power loss.
