First off, how "track" do you want? Are we talking RE-71R, NT-01, Hoosier R7, or Conti/Pirelli slicks? If you want a trackable street tire, I have to give props to the SS 1LE's Supercar 3 tire, though it's only in 20" sizes. Otherwise your closest good bet is a square 295/30-19 setup with RE-71R or 295/305 setup with Toyo R888R. If you were going Hoosier R7's, then 295/30-19 and 315/30-19 just barely fits.

I'm a fan of mr965's recommendation with NT-01's in 305/30-19 and 325/30-19, but those will obviously poke just like the same size Supercar 3R's on the ZL1 1LE.
