You don't need a jack pad, but all jacks should come with a round rubber insert on top of the jacking point, but you should ensure that the jack is solidly under the frame, there's plenty of surface area there to ensure a well placed jack should work both in front and rear. The holes there are for fitting the standard piece of **** scissor jack...a worthless contraption.
Now you mention that your's is a racing jack, just ensure it has the right lifting capability for the 5800 lbs RRS.
Cheers.
