Sorry i am newbie when it comes to FWD performance. I know they are better in the snow is all and there is torque steer. Anyways..my mustang has a rear end gear ratio and i would assume all FWD do as well. Can u upgrade them like u can rwd?? Like i have stock 3.27's right now and i am gonna go with 4.10's in the future. Anyone know what the RL is if they do have them and can that be upgraded too?
