We have to run Yokahamas we have mediums for very hot days and set softs only for the wet and a set of softs for dry cold days. Our races are 10 to 15 laps and KH is a climate on its own.We did have a set of harder compounds,but never got them working.The Porsche runs medium back soft front or medium front harder back. I was outbreaking both Morgan and Porsche in the wet and watching the Morgan squirm in front of me at corners,but it is a 4 litre which shows on the straights.
