I have 8 good Hoosier Koni Challenge 245/45
/17's - Non-DOT approved. 4 of them have 3/32 to 4/32 of their tread left (only a couple of heat cycles) and 4 have 2/32ish of their tread (maybe 6 heat cycles).
These were a bit of a challenge to get to fit on my STi. I had to space the front wheels out with a 10mm spacer.
They would be a decent track day tire if you are changing tires at the track.
I would let them all go for $300+shipping.
