Insanity Speed Elixir Aggressive Inside is the most commonly used inside tire prep in the Insanity program, designed to condition the tire compound from the inside for improved performance, durability, and race-day consistency. This prep penetrates deep into the tire, creating a stable base that enhances traction while helping maintain tire longevity across multiple race cycles.
Aggressive Inside is widely recommended for Pink Maxxis tire programs across a variety of track conditions and pairs exceptionally well with Yellow Crush as part of a balanced tire preparation strategy. When applied properly, it builds a deep conditioning base that allows racers to adjust surface grip with outside preps depending on changing track conditions.
As a general guideline, racers typically apply 1 ounce (approximately 30cc) to achieve roughly a 3-point durometer drop in warmer conditions or around 2 points during cooler weather. Once treated, the conditioning effects can remain active inside the tire for one to two months, helping maintain consistent performance between race events.
Aggressive Inside also works well with Firestone compounds, following similar application guidelines used with Maxxis tires. It is also a recommended base conditioner for Vega and Unilli tires, making it a versatile inside prep whether paired with Aggressive Outside for added surface bite or Wet Track when a soaked tire setup is required.
Application:
Designed as an inside tire treatment during mid-week preparation to condition the tire compound and build a long-lasting base before race day. Ideal for dirt oval kart racing tires where controlled durometer drop and consistent traction are needed. Often paired with Yellow Crush, Aggressive Outside, or Wet Track depending on track conditions.
