I run hillclimbs, time trials and the occasional autocross with my Caldwell D9 Formula Ford. Many of my friends now use the soft hillclimb Avon tires that are so popular in the UK and Europe. I have looked into trying a set on my Formula Ford but there isn't a viable rear tire that will work with the 5.5 inch wide rear wheels we are required to use. So I contacted Roger Kraus the west coast Avon dealer because I heard he had Avon build some special cantilever rear Formula Ford tires in the past in a soft autocross compound. He got back with me yesterday and said he is meeting with Avon engineers this week to discuss his needs and said if I could find 15 folks who would consider buying a set of these tires for autocross or hillclimb, he would have them build the minimum twenty sets they require. Now Avons will cost more than Hoosier R25Bs by about 20% depending on exchange rates and what I see from my friends who use them on the hills. Anyway, I will try a set if they are built but he needs at least 14 more customers. Who's interested? You can contact me at ffhillclimber48@gmail.com or call Roger directly at 510-582-5031.
