Insanity Speed Elixir Yellow Crush is the most popular prep in the Insanity tire program and a staple for racers looking for a versatile conditioning formula. Designed to build a strong base during the week and deliver reliable grip on race day, Yellow Crush helps maintain tire consistency while minimizing falloff throughout the event.
This prep works exceptionally well as a mid-week conditioner, allowing racers to build a deep base in the tire compound before race day. When applied during the week, Yellow Crush penetrates the tire to improve conditioning and longevity, helping the tire maintain performance across multiple sessions. On race day, it can be used as needed to help tires fire quickly and adjust grip levels depending on changing track conditions.
Yellow Crush is commonly paired with Inside Aggressive as part of a complete tire program and performs well in conditions ranging from mid-day qualifying to evening races where track moisture increases and additional bite is required. Its versatility also allows racers to run the same tires throughout the day without stacking multiple chemicals on the tire surface.
For added bite when conditions demand it but a soaked tire is not yet required, Yellow Crush can be mixed with approximately 20% Black Sand to increase surface traction. The prep works especially well with Pink Maxxis tires, and the same conditioning schedule is recommended for Firestone compounds. With Unilli and King tires, Hardtrack Outside during the day and Yellow Crush at night has proven to be a successful combination.
Application:
Apply liberally as a mid-week tire conditioner, wiping tires twice daily for two to three days leading up to race day, stopping approximately two days before racing. On race day, apply as needed to help tires fire off and adjust grip levels based on track conditions. Ideal for dirt oval kart racing tires where consistent conditioning and adaptable grip are required.
