i've seem suitcase genny+ tyrewarmer packages for less than £200. Losing the front (or rear) on cold tyres just once will cost at least that. (and I should know!) One sighting lap plus a warm-up lap doesn't get enough heat up, especially on a short circuit. Allow tyrewarmers, then people can make their own choice, but I personally would be a bit hacked off if I were taken out on the first lap by someone with cold tyres........... Cheers, Paul |
