Wilwood value?

[afterburners]

I was given a set of wilwood calipers and pistons set for the NSX during purchase. They look great and are light! There note for track (off road use) only. And not recommended to use with ABS on. I do not want to remove my ABS so I believe there used and would like to know the value of them if I were to sell them? There used and I assume there for the front wheels? I did a search and found little.
