Yellow Crush our most popular prep is a staple in the Insanity tire program. This prep is wiped during the week for conditioning and at the track accordingly. It's a very versatile prep that can be cut and mixed with others as needed to seek a decired effect per track conditions. Yellow Crush is a great compliment to our Inside Aggressive and can be used on conditions varying from a mid day qualifying to evening racing when track moisture is higher and more bite is needed. The versatility of this prep allows you to run the same tires throughout the day without having to wipe multiple chemicals on the same tires. The most commonly used mid week conditioner for pink Maxxis. Yellow Crush is applied during the week to set in a deep base for race day that will provide a lasting result and keep tire fall off to a minimum. For best results wipe liberally twice a day two to three days during the week approximately ending two days before race day. On race day use as needed to help tires fire off and adjust for the amount of grip needed for track conditions. When track bite is high for midday and qualifying this prep is recommended for two week scuffs while a fresher and deeper rolled tire is more suitable for damper race condition. When that extra bite is needed but track is not ready for a soaked tire Yellow Crush can be mixed with 20% Black Sand to achieve a tire with more bite and this has proven very successful. When using Firestone tires following the guidelines above for Pink Maxxis is recommended. With Unilli and King tires, Hardtrack Outside is recommened during the day and Yellow Crush at night. As you can see, this tire prep has many applications and is a very important part of an Insanity Speed Elixir tire program.
