The reason why I think we need stiffer flex plates is because at Cleveland and high bite tracks the rear-end is too soft. I can't say what you race on in Florida to test parts but here in Cleveland, Cincy and CEFX the traction is very high.
Glad to hear there are stiffer ones availiable. When I e-mailed BMI from Cleveland I was told there were not stiffer Flex Plates availiable.
Maybe on the website you can create a "What's New" area so that we can find out if updated parts are availiable.
