I had to make a change on my rear 19" wheels for the track because I was having problems finding a decent race tire in that size. The 19" rears are now for street wheels...

I am now running 18x8.5 front wheels & 18x9.5 rears.

The tires that I'm trying for the track this weekend are Hoosier R3S05 275/35/ZR18 slicks for the rear. And Kuhmo ECSTA V710 245/35/18 slicks for the front.

I'll be running the combo on the track for the first time this weekend and give some feedback when I get home...
