zenetti 0 Report post Posted December 9, 2009 Dunlop has a new Ultra High-Performance Tyre. The Direzza Sport Z1 Star Spec is Dunlop's Extreme Performance Summer tyre developed for serious sports car, sports coupe and performance sedan enthusiasts looking for race tyre-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 tyres to come in during initial runs, as well as drivers of lighter weight vehicles who are often confronted with the task of working tyre 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 tyres 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 tyres 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 tyre 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 tyre's internal structure includes two wide steel belts reinforced by JointLess Band (JLB) Technology spirally wound polyamide to provide strength.
