I was thinking that getting new tires at this point would make the rear more slippery, just from the new tire "molding material" or whatever. Any thoughts, should I get new tires or not.

First, I'm assuming that you're driving your car to and from the HPDE event... what will you do if you cord your tires during the event (not to mention having an actual failure on track at speed)?

Second, many tires are at their grippiest when they're new (after maybe a lap or two of warm up).
