It's actually a very good tire for the price. It's an older Dunlop design, but it sticks well and the breakaway is very predictable. The HTRZ also tends to run wider than most tires with the same numbers on the sidewall. I have a set on the rear of the S2000, and they're very easy to drive. Some of the S2000 guys have actually used HTRZs shaved down for track days and ran the fastest laps out of all the cars there.
