“Disco” Donnie Nall Introduced Insanity Speed Elixir in 2012. This line of prep contains 6 preps, two inside Preps and four outside Preps. This will allow racers to cover all race track conditions, from coldest and wettest conditions to the hottest most biting tracks from asphalt to dirt.
This prep will soften any style of tire you can throw at it. It has been tested and approved to work with any tire program from race cars to karting.
