Get them while they're hot! (See what I did there?)
Battery/12V powered, fully adjustable digital temperature setting tire warmer controller with belts. These are powered by a 12v source, which means a 3S battery works perfectly, and can provide about 45min of heat from a 5000mah battery. No special battery is needed, just a good 3s battery (sold separately here) Being able to run off a battery, and having a light compact controller means you can keep the warmers on your tires until the very last minute before your run. The temperature is fully adjustable, from 20°-110° (68°-230° in freedom units).
You get a controller and pair of belts (2 tires) which fit larger no prep slicks.
This is a must have for any drag racer!
