The Dunlop Direzza Sport Z1 Star Spec has become a staple among autocross and performance enthusiasts. Many were disappointed to hear it had been discontinued. Dunlop has launched the newest version of their highly successful Extreme Performance Summer tire, the Direzza ZII. It's designed for enthusiasts who demand race tire-like traction for street use, autocross, drifting and track events.

Direzza ZII’s high-grip tread compound is molded into a directional design with a continuous center rib flanked by massive shoulders to form a highly rigid tread that delivers high levels of dry grip and handling while promoting uniform tire temperatures and even wear across the tread. Two wide circumferential center grooves channel water through the center of the tread design. Angled independent grooves help direct water to the sides of the footprint to enhance wet traction.

The Direzza ZII features Dunlop’s True Circle Profile to distribute tire deflection forces along the sidewall to provide more control by better communicating tire performance limits to the driver. Its internal structure includes JointLess Band (JLB) Technology that spirally winds polyamide cord over two wide steel belts to promote strength, uniform ride quality and high-speed capability.

During our time testing the tire, it proved to be a worthy replacement for the Direzza Sport Z1 Star Spec with significant lap time improvements in both the dry and wet when compared head-to-head. To read the full report, take a look at "Dunlop Direzza ZII Introductory Track Drive."
