RS-3's should really be AX dedicated tires. I realize that the ones you have will currently pass inspection, but they don't have much life left on them. Especially considering they are marginal at best in the wet with full tread. I think your price is a little high. Looking for good tires for a regular car, you can find a "very good" to "almost unused" set in the $200 range. And for AX only tires there is not enough life left there to justify spending that kind of money.
Here is a thread about used racing tires (all in the same category as the RS-3's) and from the descriptions and pictures these all had considerably more life left than the ones you got.

I would actually be interested in buying these from you, they are actually the same size that I use, but honestly wouldn't waste the time, effort and money to buy these and get them mounted and balanced (an additional $60-80) unless they were in the $50 range. Because they have such little life left, I would be better off just buying a new set to race if the price was any higher than that.
Not trying to be a dink and shit on someone else's for sale thread, but you are asking just under half the cost of new and there is no were near half the life left. Those tires are just over 2/32" left of depth, oem those had 8/32"
