The 2:1 rack would be a great choice for quicker steering, however if you are thinking of adding the rack to your current quickener, I woudn't recommend doubling up - it will be way too difficult to steer. You would want to run one or the other. Once you do go to a quicker ratio, you will probably want to add the pro power steering kit as well, because it will be more difficult to turn with just the stock power steering system and you will get arm pump in the tight, twisty sections.
