Diff gears....... I can vouch for that!! My tuner rekons that my car is the quickest he has ever had to change gears. Because its so short between changes. im running the 3.9

As for down low. Yes its also true. 1st for me off the lights is usless. Unless I want to sit on the spot spinning.....

So I guess what im saying is I dont think diff gears would be one of the first things I would do again... but in time I guess I would do it. Just not first up...
