Feels like the options for smaller wheels are just becoming impossible to find, at least in the US. Europe and Japan still have lots of small new cars, so I think they have a couple more options. Even the more popular size Miatas use in 225/45/15 I can only find in 200tw, but they're so much shorter than stock, I think they always look terrible and out of proportion on the Z
Potenza sport looks okay. I think the 052 is out of the question as a 200tw, but moreso because of the cost. I'm trying to keep it under $200 per tire so I can spare some change for the wheels.
Right now I'm thinking of the Continental Extreme Contact Sport 02. They're 340tw, but supposedly slightly better on the comfort than most other options, which I have started to care more about now that the car is much nicer haha. Know the Toyo Proxes R1R are popular for some guys running 16s, but they're only in a 225/45 profile.
I appreciate the support! I know many posts have nothing people can really respond to, so sometimes it feels like you're just typing into the wind, so I appreciate that people have been enjoying the build all these years.
