I noticed that TireTrends has them for $306. They also carry Kumho ECSTA MXs. I just installed a set on my Monster Miata. (I put 215x40x17s all the way around, but next time I'll go with something a bit wider/taller, like a 225/45, because traction is always a problem with a V8 in a Miata) I've only put around 300 km on them, but so far so good. From what I've read, Kumho ECSTA MXs seem to have a very good rating. By the way, they sell for $214.37 (Tiretrends). Now, are they as good as the S03s?
