I'm selling a set of Nankang CR-S V2 tires mounted on stock C8 wheels. They were used for one track day and are in great condition. The front are 265/30ZR19 and the rears are 325/30ZR20. They are ~20mm wider than stock. The fronts are a little shorter and the rears are a little taller than stock but it didn't cause any issues like ice mode.
I paid $2600 for the wheels and tires. I'm asking $1600 picked up in the SF bay area.
