This was my spare set and I used them last season. They re the type with disconnects when removed so they cut off as you remove them....dual temp as well. They come in the factory carry bag too. I have pictures...too big to share here it seems. Message me and I can text to you. But they are just black tire warmers in great shape...no surprises. $350 + shipping or can bring to Rd ATL or Tally when we get back to racing.
