JSR tire prep is a product made for us by a reputable chemical company that specializes in Karting tire preps. It is not a mixture of mineral spirits, toluene and whatever else we could find on the shelf at lowes and home depot. We do not make it ourselves. Our goal is getting our on line of prep was to keep the tire prepping process simple and we have been able to do that. Here is what we offer:
Inside: This is a Non-Aggressive prep that will lower the durometer reading 2-3 points per 30 cc's. It does not dry the tire out and will stay with the tire for several weeks. Unlike any other inside prep on the market.
Outside: Our best seller for the outside of the tire when used along with our inside prep. Fairly aggressive but once again it will not dry out the tire.
Trackside: Without a doubt the best at the track "BITE" on the market. It doesn't take much, will dry quickly so you dont go to the grid with wet tires, and will last.
