Lockhart Phillips tire warmers and as seen here: http://www.lockhartphillipsusa.com/Tire-Warmers/ but in black, not red (black hides any grease/dirt better!). I bought them used and they have very little use by the previous owner (maybe 5 trackdays if even that). I've never used them. They are dual temp (high and low setting) and work fine with the exception of the LED on the rear tire warmer does not light up when it's on. That happens to most warmers with a LED indicator. There are a couple of very minor burn marks on the interior of the front warmer as seen in the photos. I'll sell them for $150 shipped in the US. PM or email me at email@example.com if interested.
