I should mention that your suspensions roll may increase due to 'softer' feeling springs. That is because the ALKs take up more of the energy during braking/accelerating instead of transmitting them to your suspensions' springs. This in turn will allow each wheel to independently contour to the pavement better, thus increasing traction significantly on four wheel drive vehicles. Your vehicle's corner exit speed will increase the overall speed in the straights; and as we all know, it's maximizing speeds in the straights that count toward decreased lap times the most. That's not to say it isn't important to do well in the corners, too.
