The Dunlop Direzza ZII is a very solid all-around max-performance summer tire. It has been the top choice for Autocross and track day enthusiasts for many years, and it is still an ideal tire for track day use. The tires compound warms up quickly to optimum temperatures, even on colder days that we have frequently here in Alberta, and the stiff sidewall makes the tire very responsive to turn-in.
The Dunlop Direzza ZII’s are designs primarily as an autocross and track day tire. As such, road noise levels are higher. However, these tires are some of the best tires available for track use in rainy conditions, and have also done well in periods of extended use, such as chump car endurance races.
