We finally got a new stocking order of the JPR LED Tire Warmers that had been sold out for a few months. These are very comparable to other brands on the market at a MUCH lower price! I have personally been using the JPR digital warmers and know of other friends who use the LED warmers and none of us had ever had any problems. JPR Performance offers a one year warranty against any defects though.
Its great to have warmers at the track because you can go hot right out of the gate, no warm up laps necessary and you don't have to keep wondering if your tires are finally up to temp so you can start getting on it. Also you will conserve the life and integrity of your tires by preventing them from heat cycling. Once you get used to warmers you'll never want to run at the track without them.
These are the best value for your money, why shell out a lot more for another brand that does the same thing?!
