Well I've been looking at getting a new rear end for my WS6 since day one. I know these cars are known for having weak rear ends and i'd rather spend the money now then later. The main dilemma i have is which gears to go with. So... 3.89 or 4.11?

Keep in mind that this is a daily driver, and i dont want something that will completely kill my gas mileage.
