Yeah, they run P Zero slicks now. Used to run cut down(i think) Toyo street tires with a racing compound, did make for some good races with Andy Pilgrim would come storming back through the field as the tires he saved under the Caddy helped him pass the fast starters. And maybe the best Audi commercial ever was the start of a race in the rain; think Caddy or Viper had locked out the front row. Lights go out to start and suddenly there appears the Audis out from behind the front row and around the leaders to turn 1. Was an impressive ad for Quattro.
Series might get some better pub now with F1 joining them on NBC Sports. And apparently there's some other race series on there too
