The manufacturers make a bold promise that their product is undetectable, and when that product is tyre softener you can understand why governing bodies of karting around the world have beenÂ secretlyÂ scrambling to get to grips with how they do it. Â GR700 MaxiGrip by Lexoil can apparently go undetected through tyre sniffer systems because of its unique properties.
Its aim is to generate heat quickly in the tyres as soon as there isÂ friction. It is a surface coating formula that is notÂ penetrative thus by the end of the race any traces of the product are gone. For stewards and officials who haven’t got a system to detect it, this is an absolute nightmare! TheÂ advantagesÂ for drivers who choose to cheat the system are massive, and if GR700 continues to prove to be undetectable by most current standards the risk is virtually zero. It is a body blow to those who choose to race fairly in classes where these products are outlawed.
As we understand it there areÂ laboratoryÂ testsÂ under wayÂ to get to the bottom of how to detect the product in the UK, but how widespread this problem is around the world, it is not known. It is clear that clubs and championships without parc ferme tyres may have to issue a major re-think. One solution is testing tyres before the race, but time constraints can be an issue there.
We will continue to follow the story as it develops.
