The Direzza Sport Z1 Star Spec is Dunlop's Extreme Performance Summer tire developed for serious sports car, sports coupe and performance sedan enthusiasts looking for race tire-like traction on the street or for use in autocross, drifting and track events. The Direzza Sport Z1 Star Spec is for drivers who don’t want to wait as long for their tires to come in during initial runs, as well as drivers of lighter weight vehicles who are often confronted with the task of working tire temperatures up to the point of generating peak grip.

As an evolution of the Direzza Sport Z1 and continuing to use the same tread design, the Direzza Sport Z1 Star Spec tread compound helps provide faster lap times from the start by developing more traction in temperate temperatures along with consistent grip on subsequent laps when the tires are fully warmed up. While this means the Direzza Sport Z1 Star Spec tread compound accommodates a wider operating temperature range than the original Direzza Sport Z1 and reaches its maximum grip level faster, Direzza Sport Z1 Star Spec summer tires are not intended to be driven through snow, on ice or in near-freezing temperatures.

Direzza Sport Z1 Star Spec tires confirm their “Star Spec” identity in the form of a 5-pointed star symbol branded adjacent to the Direzza Sport Z1 name on the sidewall. However, this 5-pointed star should not be confused with the same symbol often branded by tire manufacturers on the sidewalls of Original Equipment tires for BMW vehicles.

The Direzza Sport Z1 Star Spec tread compound is molded into a directional design featuring notched, continuous shoulder ribs, large intermediate shoulder blocks and a wide center rib to deliver consistent contact with the road and enhance grip during cornering. Two wide, circumferential center grooves, wavy shoulder grooves and multiple lateral grooves provide water evacuation to enhance wet traction. The tire's internal structure includes two wide steel belts reinforced by JointLess Band (JLB) Technology spirally wound polyamide to provide strength, uniform ride quality and high-speed capability while steel cord reinforced, 2-ply polyester sidewalls help resist lateral deflection to provide responsive handling and cornering stability.

NOTE: We recommend installing Direzza Sport Z1 Star Spec tires in sets of four to fully realize the benefits of the Star Spec tread compound. While the Direzza Sport Z1 Star Spec can be mixed with its predecessor in axle pairs if necessary, it is recommended that the treads be shaved to the equivalent tread depth of the existing tires.
