Old thread some of the same issue. I heard some EU picked up 6.5, I would love to see mod have some popularity in the States. Hell having 17.5 and 13.5 being more popular would be nice. I saw a interview with Hagberg talking how different mod vs stock driving styles are, The Driving style of mod might be more suitable for some drivers. I remember as a kid we had stock, super stock, mod and open mod. And we generally didn't want to hang out running stock. Times have changed.
