The Direzza Sport Z1 Star Spec is a great combination of streetable performance and grip on the track. If you're interested in pulling up to an event and driving straight out onto the track without having to change your tires, the Direzza Sport Z1 Star Spec is one of the best. In fact, it's the preferred tire of the Tire Rack Project STR team that finished a fantastic season in the SCCA Solo Competition.
The team brought home:
- Three divisional championships
- Two ProSolo class wins
- Second place overall in the year-end ProSolo class standings
- Two Tire Rack SCCA National Championship trophy positions (6th and 9th of 51)
- STRL Tire Rack SCCA National Championship
