Chris and Dan,
I run a Caldwell D9 formula ford in hillclimbs in the eastern USA. The most active group is the Pennslyvania Hillclimb Association. Their web site is
www.bmr-scca.org
I pick up a copy of Race Tech magazine sometimes and am amazed at the hillclimb specific cars in there. We generally run regular road race cars and modified street cars. Are there any video or DVD of the British hillclimbs available.
We are having trouble growing this segment of the sport over here. They use to be a part of the national road race championships until the 1970s, and more popular. I enjoy them more than wheel to wheel and autocross.
