which lsd and final drive
I don't have any experience with aftermarket LSD's, but I do have experience with aftermarket gears. Unless you are serious about drag racing, keep the stock gear ratio. If you were NA, and did most of your driving on surface streets (ie. very little highway, no road racing, no autocrossing), then lower gears would be fine. If you autocross, lower gears are going to make your car way less competitive.
