Well done Eric, we also use the Avon CR6ZZ as our optional wet weather tyre down here in New Zealand and have found them very good, a medium wet to dry track they are perfect, otherwise for dry racing we use either the Goodyear BS or the cheaper Hoosier HOTD bias cross ply equivalent, 25.5X8.5 front and 26.5X9.5 rear.
PS: im a Mustang racer but still luv the gen 1(and 2) Camaros.
