JD......I'm glad someone else on this forum is as puzzled as we are about the use of slicks, as in paragraph 3 of your post. If you have read some of my other posts you will see that I am continually asking the question.....what is the problem with slicks. Your car and ours and several others ran with these things in their day. The suspensions were designed for them, the wheels made for them, and like you we cannot get ANY decent dot rated tyres to fit our 10 inch rims.

All tyres are expensive, so that cant be an objection, and as to a performance advantage, well you hit the nail on the head when you say the heat required for the slicks to operate at their optimum, is hardly an issue in a 6-8 lap race.

Thank you for a thoughtful and comprehensive piece of writing, and I'm glad someone is on the same page as us.

I will be interested in the replys we get.
