The last tire I bought for my old Prelude SH was the Extreme Performance Summer Dunlop Direzza Sport Z1 Star Spec (Zed One). I loved how the Zed One's steering response and high grip complemented my vehicle. Many drivers have been impressed by the tire's combination of value and performance; making it a popular choice for spirited street driving, autocrossing and lapping days.
With such high marks for this tire, could Dunlop improve upon it with the release of the Direzza ZII (Zed Two)? They were able to provide us with pre-production spec tires so we could perform a comparison test. Although overall lateral grip felt similar between the Sport Z1 Star Spec and Direzza ZII, the Zed Two provided better steering response, improved lateral stability and increased acceleration grip - yielding faster times of approximately half a second in the dry and over a second in the wet. These numbers show an improvement that is huge!
We just received great news from Dunlop that most popular sizes of the Direzza ZII will be reaching our Indiana distribution center in the next few weeks. For those of you out west and down south, you can start the autocross season with the the Zed Two before I can. Unfortunately, with our snowy weather here in Indiana, I'll have to wait until April or May to try this tire on my BRZ.
Most of the 27 sizes will arrive soon, however the 205/45R17, 215/40R17, 245/40R17, 225/40R18, 285/30R18 and 245/40R19 are currently expected to arrive in March or April. Also, Dunlop is offering the Direzza ZII in 285/30R18, 245/40R19 and 275/35R19. sizes that weren't available for the Direzza Sport Z1 Star Spec.
