'Star Spec' means impressive dry grip out of the gate. Driving enthusiasts won't have to wait for their tires to 'come in' at the beginning of an event, helping to provide an edge over the field. This is also great news for owners of smaller vehicles, who sometimes struggle to work their tires up to the point of peak grip.

Direzza Sport Z1 Star Spec is a DOT-approved summer performance tire for hard-core driving enthusiasts and car-club members. The tire helps deliver superb dry traction and handling at regional car-club events like track days, driving schools, and autocross.A high-response directional tread pattern with circumferential grooves helps create a consistent contact patch on the pavement for a smooth feel and seamless transition. An optimal mold shape helps provide a consistent footprint shape and uniform pressure distribution across the footprint for enhanced cornering.
