Just got a set of Falken Ziex ZE 512s put on friday. So far I like them a lot, especially for the price (under $400 mounted and balanced for all 4). A quick scan of the internet shows them to be popular with Miata owners, which bodes well for them.
The car feels a ton better now (of course that could just be the fact that my tires have tread again...). Both ride quality and handling/responsiveness are increased. I haven't driven in wet or snow yet, though. The tread pattern looks like it should provide much better wet traction than my old tires.
I've never run Falken tires before, so I'm not sure what to expect as they see more and more use. It was either these or a set of Toyo Proxes all-seasons that would have been almost $200 more, so I went with these. So far I don't regret it.
Also, this is the first time I've ever run directional tires on any of my cars. Anything I should do differently (aside from not rotating them so they're backward...)?
One other not-so-hot side effect of these new tires is that I'm starting to feel how badly I need rear shocks. With my old tires, the back end would just come loose while turning under heavy braking. With the new ones, they stick like glue and the trunk goes all over the place. Fun...
