I understand this is a bit far-fetched, but it's worth a shot. I have this posted on other forums as well.
I bought some new tires so these Dunlop Direzza star specs are for sale. These are a year old, no track days or auto-x days on these tires. No cording, holes, plugs, nothing. There is slight inner tire wear, but you can mount that outside when putting these on your wheels. They have about 10,000 miles on them and have at least another 10-15,000 left in them. Brand new these were $800. I'm selling all 4 picked up $350 in Huntington Beach.
These would make great track tires.
All tires have same amount of tread on them. The inner wear happened when I replaced my front camber plates, added more caster and drove the car to the alignment place.
Now for pics...the outer wheels look wider because of my wide angle lens, I assure you they are all 235/40 18. The inner wear looks worse in the pics also due to the lens. It's not bad at all.
