Hello I just saw your request for the S1 cams. I just recently purchased a set of these from another guy on this forum. I paid $485 shipping included. They look great and I was told they had less then 5K on them. By the looks I definitely believe that to be true. I planned on having the cams installed, and a 60k tune up, done at my local Z shop but it turns out I dont have the time or money to do this. If interested feel free to pm me or call 916-223-2059 my name is Justin. Give me an offer but honestly $400 is the minimum plus shipping from CA but it isnt that much. Thanks let me know
